They are not equivalent. This is a generic XSLT question, so a better
forum for it would be the Mulberry XSL list. However, a few pointers:
1. Namespace nodes are not attributes in the XPath data model:
http://www.w3.org/TR/xpath#data-model
2. You should take a look at the copy instruction in XSLT for more
information. There is even an example of the canonical identity
transformation stylesheet:
