The implementation of XML hypertext in Opera 5 via CSS2
takes this approach. For example.

I have XML containing:
         <xref href="some URI>See here</xref>

The relevant part of the CSS2 stylesheet looks like this:

xref {
         text-decoration:underline;
         set-link-source:attr(href);
         use-link-source:current;
}

The downside is that CSS2 drives right up against the vertical
wall of expressive power very quickly. <sigh/>.

How long will it take the W3C to stick a REC on Python and just
be done with it :-)
