When I originally wrote that text[1], now about six years ago, I still 
thought the problems were minor and there would soon be a consensus on 
how embedded style sheets were supposed to work.

About two years ago, the CSS WG noticed that there were still no 
implementations and therefore asked the XML Core WG if they could add 
something to the spec[2], either to define it better or to say that 
fragments weren't allowed.

Since then, the question has made its round through various groups in 
W3C that each couldn't solve the problem but succeeded in finding more 
issues.

So the current situation is still that there is no spec and you can't 
expect fragment identifiers to work, except in the special case of an 
XSL style sheet embedded in an XML document. Any other kind of style 
sheet embedded in any other kind of document is unlikely to work and 
may some day even be forbidden.

I've updated the text[1] with an overview of the unsolved problems.
