If you're going to use outdated applications... I'd suggest that rather 
than prefixes, you try using the default-namespace convention. That is, 
instead of <html:a>, use <a xmlns="http://www.w3.org/1999/xhtml/">.

If the application is really namespace-unaware, that should look like an 
HTML element to it.

Note that since namespace declarations are inherited, you won't 
necessarily have to re-bind xmlns on every element. A smart serializer 
should do the Right Things in that regard.


However, my position is that outdated applications should be discarded 
in favor of ones that support new standards -- so I'd recommend that you 
solve this instead by making the whole document either HTML or XHTML 
rather than mixing the two, and then use a browser (or other tool) that 
understands the language you're actually working in.
