In `@docs/guidelines/language/basics/accessibility-in-ux-writing.md`:
- Line 267: Update the “Error Prevention” reference in the helper-text guidance
to match the intended WCAG criterion: link it to WCAG 3.3.4, or rename the label
to match the existing 3.3.1 target. Keep the surrounding guidance unchanged.
- Line 74: Update the references on the lines containing empty “#” links so each
points to the correct local anchor or relative document path; remove any
reference that lacks a valid target, while preserving the surrounding guidance
text.
- Line 187: Update the headings `Input fields / Labels`, `Text alternatives
(ALT-text)`, and `ARIA-labels` to the specified sentence-case terminology:
`Input fields and labels`, `Text alternatives (alt text)`, and `ARIA labels`.
- Line 233: Update the affected accessibility guideline text to use ASCII
punctuation throughout: replace curly apostrophes and quotation marks with
straight characters, and replace the en dash in the referenced range with “to”
or another permitted separator. Apply this consistently to the instances
containing “Don't,” “We're,” “it's,” and “req.”.
- Line 15: Remove the empty heading line at the start of the document; the
frontmatter already supplies the page title, so the generated page must not
contain an empty h1.
- Around line 503-570: Update the interactive-control table and the final
landmark guidance to require accessible names only when repeated landmarks need
distinguishing. State that repeated landmarks should use aria-labelledby with an
existing visible heading, or aria-label when no visible label exists, and
describe banners and main separately from navigation landmarks.
- Line 217: Update the required-field guidance near the asterisk instruction to
explain its meaning before first use and associate it with the field label or
group legend; recommend native required semantics for standard controls or
appropriate validation with aria-required="true" for custom controls, and
replace the label-in-name citation with relevant W3C H90 guidance.
- Line 31: Update the introductory accessibility guidance to describe aria-label
as an attribute that can provide an accessible name for a nameable element when
no suitable visible label or other labeling mechanism is available; remove the
inaccurate “hidden tags” characterization and narrow buttons-and-links wording.
- Around line 454-470: Update the alternative-text guidance around the non-text
content examples to distinguish informative content from decorative images:
require appropriate equivalent text alternatives for informative non-text
content, while directing authors to use alt="" or another established method to
hide decorative images from assistive technology. Keep the existing examples and
WCAG reference aligned with this qualification.
- Line 427: Update the automatic-audio guidance to distinguish the WCAG minimum
from the project recommendation: allow either pause/stop controls or independent
volume control for audio over three seconds, then explicitly recommend providing
pause, stop, and independent volume controls, including for shorter audio.
- Line 555: Revise the accessibility guidance around “Never use aria labels” to
allow aria-label when it preserves the complete visible label and adds necessary
context for otherwise indistinguishable controls. Update the “Submit” example to
reject aria-label values that omit or alter “Submit,” and distinguish
aria-describedby for supplemental descriptive text.
- Line 401: Update the audio-label guidance around the “Play” example so the
restriction applies only when a page contains multiple audio controls. Preserve
“Play” as valid for a single audio control, and move it to the recommended
examples or explicitly qualify it as invalid only in the multiple-control case.
- Line 42: Replace the six internal ix.siemens.io documentation links with the
specified repository-relative Markdown links, preserving their existing
references and text. Keep external W3C links absolute.
- Line 128: Replace the single unordered-list item containing
line-break-separated steps with an ordered list, using one list item for each
step so the sequence is conveyed correctly to assistive technologies.

official unified remark-parse mdast empty ATX heading remark-rehype empty heading behavior
💡 Result:
<search_synthesis>
In the Unified/Remark ecosystem, an empty ATX heading (e.g., # ) is parsed according to the CommonMark specification [1]. When remark-parse encounters such an input, it generates a valid heading node in the Markdown Abstract Syntax Tree (mdast) [2][1]. Because the heading contains no inline content, the children array of the resulting mdast heading node will be empty [3][4]. When remark-rehype processes this tree to convert it to HTML (hast), it uses a default handler for heading nodes [5]. This handler maps the mdast heading node to an HTML element (e.g., <h1>, <h2>, etc.) and sets the element's children to the result of processing the mdast node's children [5]. Since the mdast node's children array is empty, the resulting HTML element will also be empty (e.g., <h1></h1>) [5]. In summary: 1. remark-parse creates a heading node with an empty children array [3][4]. 2. remark-rehype converts this into an empty HTML element tag [5]. This behavior is consistent with the standard Markdown spec, which does not forbid headings without content [1]. If you require specific behavior for empty headings (such as removing them or adding placeholder text), you can implement a custom plugin to transform the mdast tree before it reaches remark-rehype [4].

Remove the empty H1.
The MDX pipeline converts # into an empty <h1> element. Frontmatter does not remove this heading. Delete the line because the frontmatter already provides the page title.

Use consistent sentence-case terminology in headings.
Rename Input fields / Labels to Input fields and labels, Text alternatives (ALT-text) to Text alternatives (alt text) and ARIA-labels to ARIA labels. This matches the terminology used in the body text and avoids treating an attribute spelling as a heading.

W3C WCAG required fields asterisk required aria-required programmatically determined
💡 Result:
<search_synthesis>
W3C’s guidance is that a required-field indication should be both visible to users and programmatically conveyed; an asterisk alone is not sufficient, and aria-required="true" alone is not sufficient for WCAG conformance. The recommended pattern is: 1. Give the field a proper programmatic label. 2. Include a visible indication—preferably the word “required”; an asterisk is acceptable if its meaning is explained before the first use. 3. Expose the required state in HTML with the native required attribute, or with aria-required="true" where appropriate. For example: html <p>Required fields are marked “required”.</p> <label for="email">Email <span aria-hidden="true">(required)</span></label> <input id="email" name="email" type="email" required> An asterisk version is also supported by W3C’s technique: html <p>Required fields are marked with an asterisk (*).</p> <label for="name">Name <abbr title="required">*</abbr></label> <input id="name" name="name" type="text" required> W3C’s H90 technique says the required status should be indicated in the control’s label, or in the legend for a radio-button or checkbox group, and that the meaning of a non-text symbol must be explained before the control using it. [1] W3C’s ARIA2 technique explains that the visual indication may otherwise not be programmatically determinable. It recommends aria-required="true" as an additional programmatic indication when a field is visually marked required, including when an asterisk is used. However, W3C classifies ARIA2 as advisory for WCAG 3.3.2 because aria-required="true" without a visual indication is not perceivable to most users. [2] For native HTML controls, prefer required rather than adding redundant ARIA. The native attribute communicates the constraint to assistive technologies and also participates in browser constraint validation; aria-required communicates the state to assistive technology but does not itself enforce submission behavior. [3][4] If using a custom ARIA widget rather than a semantic HTML form control, use aria-required="true" on the actual form-control role and implement the required validation behavior yourself. [3] Practical conclusion: * is not a WCAG-required character, and WCAG does not require an asterisk specifically. The requirement is that users can understand which fields are required and that the required state is programmatically determinable where applicable. The most robust implementation is visible “(required)” plus native required; if an asterisk is used, explain it in text and associate it with the label or group legend. W3C’s own draft Easy Check notes that asterisks may be missed visually and often are not announced by screen readers, so the word “required” is the clearer choice. [5]

Document programmatic required state.
The 150% font size improves the asterisk's visibility, but it does not expose the required state to assistive technologies. Explain the asterisk before its first use and associate it with the field label or group legend. Use the native required mechanism for semantic controls, or suitable validation with aria-required="true" for custom controls. Replace the label-in-name citation with relevant guidance such as W3C H90.

W3C WAI landmark labels multiple landmarks same type unique landmark aria-label
💡 Result:
<search_synthesis>
According to W3C WAI guidance, when multiple landmarks of the same type (role) are present on a single page, each instance must be given a unique and meaningful accessible name [1][2][3]. This allows screen reader users to distinguish between the regions and understand their specific purpose [3][4]. Best practices for implementation include: 1. Use aria-labelledby: If there is existing, visible text on the page (such as a heading) that identifies the region, use aria-labelledby to reference that element's unique ID [2][5][4]. This is generally preferred as it leverages existing content [5]. 2. Use aria-label: If no suitable visible text exists to serve as a label, use aria-label to provide a concise, descriptive name for the landmark [1][2][5]. Key considerations for labeling landmarks: - Avoid including the role name in the label (e.g., avoid "Navigation Navigation"), as assistive technologies already announce the landmark role [2]. - Ensure labels are unique unless the content and function of the landmarks are genuinely identical (e.g., identical pagination controls appearing in two locations) [2][3]. - If a landmark is used only once on a page, it may not require a label, though labeling is often recommended for clarity [2][3]. These principles apply both to ARIA landmark roles and to their semantic HTML equivalents (e.g., <nav>, <main>, <search>) [4].

Require landmark labels only when they distinguish repeated landmarks.
The table places banners, search and main/navigation landmarks in a list of controls that "require aria labels". A single banner, main or navigation landmark does not generally need a label. When the same landmark type appears more than once, give each instance a meaningful accessible name that distinguishes its purpose. Use aria-labelledby for an existing visible heading or aria-label when no visible label exists. Update the table and line 570 to state this rule. Line 570 should also avoid describing banners and main as navigation landmarks.

W3C aria-label accessible name element no visible text definition
💡 Result:
<search_synthesis>
The W3C defines an accessible name as a short, string-based label for a user interface element that provides assistive technologies (AT) with a clear, concise identification of the element's purpose [1][2]. The aria-label attribute is an explicit mechanism for authors to provide this accessible name when no suitable visible text content is available to serve that role [2][3]. According to the W3C Accessible Name and Description Computation (AccName) specification, the aria-label attribute is evaluated as a primary "author-provided" source for the name, provided that the element's role supports naming [1][4]. Key technical aspects include: 1. Invisible Labeling: aria-label creates an accessible name that is not visually rendered, making it ideal for elements like icon-only buttons (e.g., an "X" button for closing a dialog) [2][5]. 2. Precedence and Hierarchy: aria-label is part of a computation hierarchy [6][1]. If an element has an aria-labelledby attribute, that attribute will take precedence over an aria-label [6][3]. If both are absent, the browser attempts to derive the accessible name from visible text content (e.g., button text, image alt text) [1][7]. 3. Role Support: Authors must only use aria-label on elements that support "name from author" [1][7]. If an element's role prohibits naming (as specified in the WAI-ARIA roles list), aria-label must not be used [1][4]. 4. Behavior: When applied to elements that support "naming from content," aria-label will hide the descendant content from assistive technologies and replace it with the label value [2]. For most other elements, it provides the name while the content remains accessible [2]. The W3C recommends preferring aria-labelledby over aria-label whenever there is existing visible text in the document that can be referenced to label the element [3][5].

Describe aria-label as an accessible-name mechanism.
aria-label is an attribute, not a hidden tag. It can provide an accessible name for a nameable element when no suitable visible label or other labeling mechanism is available. The later guidance covers inputs, menu controls and landmarks, so limiting this statement to buttons and links is inaccurate.

WCAG 2.2 1.4.2 Audio Control pause stop volume independently system volume
💡 Result:
<search_synthesis>
Under WCAG 2.2 Success Criterion 1.4.2 (Audio Control), if any audio on a web page plays automatically for more than three seconds, the site must provide either a mechanism to pause or stop the audio, or a mechanism to control the audio volume independently from the overall system volume level [1][2]. This requirement is a Level A success criterion, meaning it is a fundamental accessibility requirement [1][3]. Key points regarding this criterion include: Independence from System Volume: Both the mechanism to pause/stop the audio and the mechanism to control the volume must operate independently of the device's overall system volume [4][5][6]. The intent is to ensure that users—particularly those who rely on screen readers—can silence or adjust the background audio without silencing the audio output (speech) from their assistive technology [4][7][6]. Muting the system volume is explicitly not considered a valid way to meet this requirement [4][8][6]. Definition of Volume Control: Having the ability to control volume includes the option to reduce the audio volume to zero [4][3][6]. Scope of "Automatic": In this context, "plays automatically" refers to audio that is not triggered by a direct, intentional user action [5][6]. Non-Interference: Because audio that cannot be controlled can interfere with a user's ability to use the entire page (e.g., by drowning out screen reader output), this criterion applies to all content on the web page [4][1][6]. The primary goal is to prevent automatically playing audio from creating an accessibility barrier that renders the page unusable for users who depend on audio cues from assistive technologies [4][3][6].

WCAG 1.4.2 allows either a pause-or-stop mechanism or independent volume control. Requiring pause, stop and independent volume controls is permissible as stronger project guidance, but the current imperative wording and WCAG link do not distinguish it from the WCAG minimum.

WCAG 2.2 1.1.1 decorative non-text content alt empty
💡 Result:
<search_synthesis>
Under WCAG 2.2 Success Criterion 1.1.1 (Non-text Content), content that is purely decorative or used only for visual formatting must be implemented so that it is ignored by assistive technologies (AT) [1][2][3]. For HTML image elements (img) used for decorative purposes, this is achieved by providing a null (empty) alt attribute: alt="" [1][4][5]. Key requirements and best practices include: - Do not omit the alt attribute: You must include the attribute even if it is empty (alt=""). If the alt attribute is entirely missing, many screen readers may announce the image's file name or its URL instead, which violates the requirement to ignore the content and creates a poor user experience [4][5][6][7]. - Avoid descriptive text in alt attributes for decorative images: Providing text such as alt="spacer" or alt="image" is considered a failure (F39) because it forces assistive technology to announce non-meaningful information to the user [2][6]. - Contextual determination: Whether an image is decorative is a judgment made by the author based on context [4][7]. An image that is decorative in one location might be informative in another [4]. - Alternative methods: While null alt text is the standard for img elements, other methods for hiding decorative content include using CSS background images (which are ignored by AT by default) or applying ARIA techniques like role="presentation" or aria-hidden="true" (though support for these can vary depending on the element type and browser/AT combination) [1][5][8][9]. By properly implementing these methods, you ensure that screen reader users can navigate the page without being distracted by decorative elements that offer no functional or informative value [4][6][7].

W3C label in name aria-label visible text additional context accessible name
💡 Result:
<search_synthesis>
According to W3C specifications, the accessible name of a user interface element is computed using the Accessible Name and Description Computation algorithm [1][2]. When both an aria-label attribute and visible text are present, aria-label generally takes precedence, effectively overriding the visible text as the element's accessible name [3][4]. Key points regarding the relationship between aria-label, visible text, and accessible names include: Priority in Calculation: The computation algorithm prioritizes specific attributes and mechanisms over others [1]. Attributes such as aria-labelledby and aria-label are calculated before the "Name From Content" step (which uses visible text), meaning they override native semantics [1][3]. WCAG Label in Name (2.5.3): To support speech recognition users, WCAG Success Criterion 2.5.3 requires that the accessible name contains the visible text label in its entirety [3][5]. If an author uses an aria-label that does not include the visible text, speech recognition users may be unable to trigger the control using the visible label [4][6]. Handling Additional Context: - If additional context is needed beyond the visible label, W3C recommends including the visible text within the aria-label or aria-labelledby string, ensuring the visible label remains the start of the accessible name [5][7]. - Alternatively, the Accessible Description (often implemented via aria-describedby) is the preferred mechanism for providing additional context [3][5]. Unlike the accessible name, content provided via aria-describedby is announced as a description, which does not replace or override the accessible name and therefore does not interfere with the Label in Name requirement [3][5]. In summary, while aria-label provides a powerful way to define an accessible name, it must be used carefully to avoid disconnecting the accessible name from the visible UI, which can cause accessibility barriers for users relying on speech input or screen readers [3][8][4].

Allow accessible names that preserve visible labels.
Do not prohibit every aria-label on a control with visible text. If several buttons display "Submit" but perform different actions, aria-label="Submit order" can provide the needed context. Because aria-label replaces the name derived from the button content, the accessible name must contain the complete visible label to satisfy WCAG 2.5.3. Use aria-describedby when the extra text should remain a description instead of changing the accessible name. Revise the example to reject labels that omit or alter "Submit", not labels that include it.
