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

SimonSapin has just created a new issue for 
https://github.com/w3c/csswg-drafts:

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