Maybe we have a different understanding of what is
hierachical  ?

http://www.w3.org/TR/xhtml1/strict

Do I understand right that version 2 would cause

http://www.w3.org/TR/xhtml2/strict

By the way -  XT is now using

xmlns:xsl=http://www.w3.org/XSL/Transform/1.0

This is smart. ;-)

In opposite , the article
( http://www.jclark.com/xml/xmlns.htm )
( by the same author! ;-) shows us:

xmlns:HTML="http://www.w3.org/TR/REC-html40

Isn't it *not* that smart?

Would't it be better to have:

xmlns:HTML="http://www.w3.org/HTML/4.0

instead ?

When I upgraded to the new version of XT,
it was very polite for XT  to notify me that I should
change my good old stylesheet to use that new
namespace.

I guess that my *next* upgrade would go even smooter,
because current namespace is providing some clue
because of it's hierarhical form.

Rgds.Paul.

PS. Actualy there are still some more problems, but thinking
about more complex things would be easier after I'l understand
some simple things.
