Re: [XBL] Is CSS support required?

It doesn’t say anywhere that it isn’t required, and there is a lot of
text and examples in the document that uses or describes processing
with CSS.  The only optional-ish language I could find was in section 2:

  XBL user agents that support CSS should act as if they had the
  following rules in their UA style sheet:
  …
  XBL user agents that do not support CSS should not render the XBL
  elements other than the div element, which they should render as a
  paragraph-like element.

In the Conformance section, it states:

  XBL user agents must behave as described by this specification, even
  when faced with non-conformant XBL subtrees.

but it doesn’t say that the CSS parts are optional.

> (It's not required, nor is ECMAScript.  Selectors is.)

I think it should be made clearer in the Conformance section.

Thanks,
