I've been looking back over the specs for XSLT 1.0 and
2.0, and the data models for XPath 1.0 and 2.0, and
I'm not so sure the pessimism is warranted. As far as
I can tell, it is perfectly possible to create an XSL
1.0 transform that writes a result tree whose
namespace nodes have expanded names with an empty
local part--a.k.a. the namespace prefix--and also
perfectly possible to make an XSL 2.0 transform that
writes a result tree whose namespace nodes have empty
prefix properties. So it's possible to write a result
tree that can be serialized as a valid XHTML document.
The catch is that some parts of the XSLT specs give
more freedom than others on what namespace nodes can
be written to the result tree.
