While xslt1 recognices default namespaces, xpath1 does not. The only way to
specify the namespace for xpath1 is the explicit prefix.

A few remarks might help in understanding what happens to you.
- get rid of unused namespaces by using exclude-result-prefixes on the
- "xmlns" might look like an attribute but it is _not_!
- if you create an element in a certain namespace, you can _not_ change the
  namespace later on as the namespace have become an integral part of the
If you have an element "mmm" in a certain namespace (or in no-namespace) in
your input, and you want to copy it to the result, its namespace gets
copied with
it. If you want to output an element "mmm" with a different namespace the only
way is to create such an element in your stylesheet and add it to the
output tree.

Hope this helps,
