Is service.id REQUIRED or OPTIONAL?

[titusz]

The specification contains conflicting information.

[msporny]

Good catch @titusz, I expect that we'll land on "service.id is optional".

The group discussed this today and agreed that service.id is optional.

w3c/cid#160

brent: Service ID required or optional, number 160.

brent: This is marked class 3 with a discuss label. I should remember deep in my bones what class 3 means ... but it's ... what?

manu: You are clarifying or modifying conformance of existing implementations. Either making something previously non-conformant => conformant or vice versa. Here this is clearly contradictory and we need to clarify. I recommend we make this property optional.

manu: We just need to strike the "id" bit that says each service needs to contain these properties.

brent: Ok, I will label this as errata in addition to the class 3 label and we can and will address it.

brent: Any objections?

brent: Not hearing any objections. We're at time.

brent: Thank you everyone for being here, thanks Dave for scribing and I look forward to seeing task force meeting invites, reach out if you need any help getting things on the official calendar, you are all fantastic, it's a pleasure working with you.

dlongley: You're welcome!
