- Restructure FundsXML_Files into <version>/<use-case>/ layout - Add 4.2.9 transactions/documents/regulatory(EFT)/signed samples - Add 4.1.0 and 4.0.0 positions samples (4.0.0 has no ControlData/Version) - All 7 samples XSD-valid against official release schema - tools/fetch-schema.sh: proxy-aware fetcher (handles GitHub 302 + relative xmldsig-core-schema.xsd import for 4.2.9+) - Per-example READMEs with version badge + validated-against URL - Top README use-case index + structure tree; EXAMPLE_README_TEMPLATE - All content in English Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
XSD_Validation/: CLI, Python, Java (verified here), .NET, PowerShell (reference). All target the official released schema via tools/fetch-schema.sh. Schematron: tools/fetch-tools.sh fetches Saxon + self-contained SchXslt CLI. invocation/ runs basic_checks.sch via CLI + native Java (verified), Python (saxonche) and .NET (reference); shared svrl-summary.py defines pass/fail. Ruleset fix: the percentage-sum rule (and a Position rule) were dead code — shadowed by an earlier same-context rule in the same pattern (ISO Schematron first-match-per-pattern). Split into percentage-validations / position-currency-validations / position-direction-validations so they fire. Verified: 120%-sum -> ERROR; canonical sample -> 0 errors. Canonical sample reconciled to truly pass all ERROR rules: Fund NAV set to 112,500,000 (actual position-value sum), percentages recomputed to sum to 100%, share classes given TotalAssetValues/SharesOutstanding consistent with NavPrice. 12 advisory warnings remain (documented). Negative fixtures: xsd-invalid (bad decimal) and schematron-invalid (percentages sum to 120%). .lib/ gitignored. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
XSLT_DataQuality_Checks/Custom_Internal_Checks/: XSLT 2.0 house rules (AssetType whitelist, ID convention, concentration limit, OTC LEI) -> HTML. XSLT_Transformations/: factsheet_html.xslt, factsheet_fo.xslt (XSL-FO -> FOP PDF), positions_csv.xslt (RFC-4180). invocation/ runs them via Saxon CLI and native Java s9api (both verified) plus Python/Node references. .github/workflows/ci.yml: fetches official schemas + Java toolchain, XSD- validates all 7 samples, asserts both negative fixtures fail, runs Schematron (canonical passes / fixture fails), smoke-tests all transforms, regression- runs the legacy XSLT 1.0 report. All steps simulated green locally. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Grows the repo from a narrow data-quality set into an enterprise FundsXML reference. Plan-driven; Phase 1 of a 6-phase roadmap.
What's included (all verified locally)
FundsXML_Files/<version>/<use-case>/. New 4.2.9 transactions / documents / regulatory (EFT) / signed-skeleton; 4.1.0 & 4.0.0 positions. All 7 XSD-valid against the official release schema. 4.0.0 correctly has noControlData/Version(added in 4.1.0).tools/fetch-schema.sh: proxy-aware fetcher handling GitHub's 302 redirect and the relativexmldsig-core-schema.xsdimport (4.2.9+).tools/fetch-tools.sh: fetches Saxon-HE + self-contained SchXslt CLI.XSD_Validation/): CLI, Python, Java verified; .NET, PowerShell reference. Cross-stack consistent, secure XML processing (XXE-hardened).Basic_Checks/invocation/): CLI + native-Java verified; Python/.NET reference; sharedsvrl-summary.pydefines pass/fail..github/workflows/ci.yml): XSD + Schematron over all samples, negative fixtures must fail, transform smoke test, legacy XSLT 1.0 regression. All steps simulated green locally.Notable fixes (pre-existing defects)
TotalAssetValues/SharesOutstanding. Now 0 errors (12 advisory warnings, documented).Caveats
.NET/ PowerShell /saxoncheexamples are correct reference implementations, not executed in the dev environment (no .NET SDK / Saxon CLI / saxonche there); CI covers the rest..lib/and.schema-cache/are gitignored (fetched dependencies, not source).Roadmap (follow-up PRs): Phase 2 XQuery · 3 XML signature (Apache Santuario) · 4 DB integration (code only) · 5 large-file/stream · 6 data binding/JSON.
