I completely agree with your post.

How about this translation of css?

<css:stylesheet>

<css:rule match=[XSL_match_pattern]
  [css_attributes]
  />

<css:media type='print'>
  [css_rules]
</css:media>

</css:stylesheet>

Where [XSL_match_pattern] is an XSL match pattern and [css_attributes] are exactly the
attributes in the css spec.

XSL match pattern has the following extensions:

OtherMatchExpr ::= PredicateExpr

PredicateExpr ::= link()
                | visited()
                | active()
                | hover()
                | focus()
                | lang(c)
                | is-id(constant)

Examples taken from the CSS2 spec:

<css:rule match='SPAN[hello="Cleveland" and goodbye="Columbus"]'
          color='blue'/>

<css:rule match='A/link()' color='red'/>

<css:media type='print'>
  <css:rule match='BODY' font-size='10pt'/>
</css:media>

// supporting @page
<css:rule match='page()/left()' margin-left='4cm'/>

<css:rule match='H1/before()'
  content='"Chapter " counter(chapter) ". "'
  counter-increment='chapter'
  counter-reset='section'/>

<css:rule match='H1|H2|H3' font-style='italic'/>

<css:rule match='D'
          display='inline'
          font-weight='bolder'/>
