Re: [xsl] xslt svg problem

[tcn at melvaig dot co dot uk (Trevor Nash)]

If you look in the SVG DTD you will find that it plays a little trick
on you: it has a default namespace declaration for the svg element.
This means that if the DTD is used the <a> element is not in the null
namespace, its in the SVG one.

This means you either have to not read the DTD (as you discovered,
this works) or declare the SVG namespace in the stylesheet and say
match="svg:a" instead of match="a".  The second is more correct.
