[css-cascade-6] What is the desired shape of CSSScopeRule? (original) (raw)

In #8468 @andruud pushed a spec definition for adding CSSScopeRule to CSSOM:

    [Exposed=Window]
    interface CSSScopeRule : CSSGroupingRule {
      readonly attribute CSSOMString start;
      readonly attribute CSSOMString end;
    };

As far as I can tell, this change in the spec never had a resolution attached – so bringing it up here to get that resolution. In conversation with @fantasai, she also raised a few questions about the final shape of this rule:

• Is 'start'/'end' the terms we want? Or do we want 'root'/'floor', or any number of other things. Since this is the only place in which the terminology is actually user-facing, it becomes a real question.
• Should they return null string or null if they're missing?
• Do they include the wrapping parentheses or not?
