cdoublev has just created a new issue for https://github.com/w3c/csswg-drafts: == [css-values-5][css-property-values-api-1] Case-sensitivity of identifiers from `<syntax>` == In this issue, I use `@property/initial-value` as an exemple and assume that it will be defined with `<syntax>` at some point, because `<syntax>` is otherwise only used in features that are not yet implemented in any browser. ```css @property --registered { inherits: false; initial-value: RED; syntax: red; } ``` The above code results to an invalid rule in current version of Chrome and FF (at least). > The [initial-value](https://drafts.css-houdini.org/css-properties-values-api-1/#descdef-property-initial-value) descriptor’s value must [parse](https://drafts.css-houdini.org/css-properties-values-api-1/#consume-a-syntax-definition) successfully according to the grammar specified by the syntax definition. **Aside:** *"parse"* links to an incorrect algo, as reported in w3c/css-houdini-drafts#1111, if I am not mistaken. However, this code results to a valid custom property value: ```css @property --registered { inherits: false; initial-value: red; syntax: red; } div { --registered: RED; } ``` Similarly, the new [parse with a syntax](https://drafts.csswg.org/css-values-5/#parse-with-a-syntax) algo is not quite clear on case-sensitivity: > 3. parse `values` according to `syntax` Should it parse `values` case-insensitively, with the serialization of `<syntax>`, or against a grammar defined with enforced case-sensitivy because `<syntax>` produces `<[custom-]ident>`? In hindsight, authors may or may not want case-sensitivite matching. For exemple, they might want case-sensitivity for `animation-name`s, but case-insensitivity for color names. Perhaps `@property/case-sensitive` defined as `true | false` (initial: `true`) may be a solution to clarify the expected behavior?
