[css-fonts] Grammar of <feature-value-name>

[SimonSapin]

The grammar for the value of font-variant-alternates https://drafts.csswg.org/css-fonts/#propdef-font-variant-alternates links its values to their respective definitions, for example stylistic(<feature-value-name>) is i link to https://drafts.csswg.org/css-fonts/#stylistic.

However once we’re there, stylistic(<feature-value-name>) is repeated but without any link. I couldn’t find the definition for the grammar of <feature-value-name>. Based on reading other sections of the spec I think it’s supposed to be a single identifier. There should be a definition (maybe <feature-value-name> = <custom-ident> ? https://drafts.csswg.org/css-values/#custom-idents) and it should be linked every time <feature-value-name> is used elsewhere, like for example in https://drafts.csswg.org/css-fonts/#stylistic.

<dael> Topic: [css-fonts] Grammar of <feature-value-name>
<dael> github: https://github.com//issues/1000
<dael> Chris: No one has commented since Feb.
<dael> Chris: Part of the issue is because this is pre-bikeshed spec we don't have a good link into grammar part of CSS.
<dael> Chris: Is Simon on the call?
<dael> astearns: Is this strictly editorial or is there a problem with grammar because link isn't set up correct.
<dael> Chris: Grammar problem. Is this a single identifier or is it not.
<dael> Chris: I would be okay getting back to Simon asking for more details on what's the issue.
<dael> astearns: Okay. Anyone else have any...can anyone else bring clarity to this?
<dael> astearns: Let's tag Simon and get more information.
<dael> Chris: Thanks very much. I yield the floor.
<dael> astearns: Thanks for going through this to make sure fonts has a good DoC

Yes, this is editorial. Since filing this issue https://drafts.csswg.org/css-fonts/#propdef-font-variant-alternates has changed and <feature-value-name> now is linked. It goes to https://drafts.csswg.org/css-fonts/#typedef-feature-value-name

The identifiers used within feature value definitions define <feature-value-name>s and follow the rules of CSS user identifiers and are case-sensitive.

… which seems to be a convoluted way of saying <feature-value-name> = <custom-ident>. Let’s call it good enough.
