No it's correct - namespaces operate at the XML level, not the XSLT
level.
But the XSLT level relies on the XML-level namespaces in context.
I often get confused about that, and think that somehow import
precedence would allow you to do what you are trying to do, so you're
no alone.
Since XSLT files are XML files, and each imported or included XSLT
stylesheet has to be a properly formed XSLT stylesheet, I think the
current specification is most appropriate.
To be honest, I'm not too sure things are correct as they stand now.
A prefix used in an XPath doesn't stop the XML from being namespace
well-formed, so I don't see why that namespace needs to be declared in
that particular file. It seems an artificial restriction.
Not to me. Importation and inclusion doesn't happen at a syntax
level, it happens at a semantic level. Therefore, building the
semantic components of an XSLT stylesheet has to happen solely from
the XML syntax being used to express the components, not to any
contextual use of the syntax by other copmonents.
To fix your problem, you could just define two different prefixes, say
"w" and "w2" for example (not for real) and then modify all of your
stylesheets to handle both... not great I know. Or if possible just
match on *. Or alternatively do a 2 pass transform and convert the
input to use the other namespace, then process as normal.
I'm not sure about the conversion ... if you transform an OOXML <p>
into a WordML <p> then when it comes time to act on <p> you don't
know which it really means.
I hope this helps.
