? This is only true of top-level params, is it not? I am quite 
convinced that intra-stylesheet xsl:params can be result tree 
fragments, like any variable.

I looked at the code, and I have to agree it is not a two-liner.

Fair.

Hmmm... If I may add my chime to this, I have a use case where I call a 
transformation from within another transformation. I would want to 
access fragments of the calling document from the stylesheet. I may 
call the substylesheet on many distinct fragments of the calling 
document, so access to the top-level document is not quite adequate.
Worse, the original document may be an in-memory document, generated 
on-the-fly, and hence has no URL that I could use to access it from the 
document function().

Just wanted to add my +1 to this request.
