[lxml-dev] Does lxml/libxslt support passing in nodes as xsl:param parameters?

[Paul Everitt]

I believe the answer is no.  I can't tell if this is part of the spec, 
but docs on other processors imply that you can use a node or node list 
as the value of a parameter passed to a transformation.

In my use case, I'm trying to get information from the current web 
request.  I don't want to modify the input document (my normal way to do 
this.)  Thus, an XPath extension function or a document resolver will 
have to serve the purpose.

This will be tricky, because I'll have to do a thread local or something 
to know I'm grabbing a *particular* request.

Perhaps I need to ponder this.  I must be looking at it the wrong way. 
I want to make sure I don't reparse the input document (it might be 
pretty big) nor the XSLT processor.
