Not quite. A template of 'P' would match all elements that have a local
name 'P', regardless of the namespace they came from, *unless* another
template was more precise. For example:
do this most times
but do this on others
and do this for anything in one
XSLT uses a scoring mechanism to work out which template should be used
when there is ambiguity.

I think each XML grammar needs its own namespace, since we want to be
able to mix documents within 'documents' all over the shop in manners
that we had never thought of in advance. We therefore need EVERYTHING to
be XML 1.0+namespaces.
