Sorry, I should have been more specific. CSS1 is -- I believe -- fully
implemented in Mozilla [1] which will form the basis for Netscape 5.x.
As you have notices, Netscape 4.x has quite crappy CSS support and
Netscape employees are the first to admit it.

Opera's CSS1 support in 3.6 (currently shipping) is the best on the
market [2] but not quite complete. The few remaining holes have been
filled, but not yet shipped. The next version will support XML as well
as a number of other MLs.

There was no XML, but there was SGML. The CSS1 Recommendation notes:

  "We expect to see extensions of CSS in several directions:

    - other DTDs: CSS1 has some HTML-specific parts (e.g. the special
      status of the 'CLASS' and 'ID' attributes) but should easily be
      extended to apply to other DTDs as well."

The CSS2 Recommendation is fully XML-aware:

  "This specification defines Cascading Style Sheets, level 2 (CSS2).
   CSS2 is a style sheet language that allows authors and users to attach
   style (e.g., fonts, spacing, and aural cues) to structured documents
   (e.g., HTML documents and XML applications)."
