Right, the XPath engine uses both ->namespaces and ->nsHash.

I meant that you should only use string or integer literals in parameter
values and no other XPath expressions at all. This means to rework your
stylesheets, of course.

I think I'll stick with my solution to add the namespaces to the xpath context. :)
Is there any reason why path parameters with namespaces haven't been supported?
Would a pull request to add the namespaces in xsltNewTransformContext be considered?
