keithamus has just submitted a new pull request for https://github.com/w3c/csswg-drafts:
== [css-color-hdr-1] use one-or-more for `dynamic-range-limit-mix` grammar production ==
Based on the parsing tests in WPT (https://github.com/web-platform-tests/wpt/blob/master/css/css-color-hdr/parsing.html) it seems as though commas are _required_ for each set of ident && <lengthpercentage> groups here, however the spec is using the `+` sigil which allows for "one or more" but doesn't specify commas. I think what might be desired here is to use `#` which is "one or more comma separated". This would satisfy the requirement for commas.
I think, in addition, we might want to specify something like `#{2,}` - considering all examples in the parse tests expect two or more values, and the spec talks about summing all values, I am unsure if it is redundant or not to specify just one value (e.g. `dynamic-range-limit-mix(high 10%)`).
This doesn't resolve the recursive affordances that the WPTs allude to, but baby steps 😆
