[css3-images] CSS element reference identifier from L. David Baron on 2012-02-05 (www-style@w3.org from February 2012) (original) (raw)

http://dev.w3.org/csswg/css3-images/#element-reference (Overview.html revision 1.269) says the following:

(CSS does not define how an element acquires a CSS element

reference identifier; that is determined by the host language.)

I think this should have more useful text. For example, it could say:

For example, for [HTML5], see the definition of CSSElementMap at ....

Even better, it could perhaps even define the behavior for HTML, but allow other languages to define different behavior.

I think specifying features in CSS that require the host language to define something, without giving any hint as to what happens for the common use case, is a bad idea. It makes it hard for readers of the specification to figure out how to use the language, and it has the potential to create a gap between specifications that's never filled in.
