Ah, I missed that.  When I was stepping in with a debugger all I noticed was
ctxt->tmpRVT which looked like it persisted for the duration of the transform
context, I understand how it works now.  Changing my stylesheet to use more
templates should minimize the consumption.  

Aggressive dictionary use would also help.  Currently I used a lot of
xmlNewTextChild() to build the result tree fragment in an extension, which in
my case contains a lot of repetive element names.  Is there a way to use the
transform's dictionary to minimize memory usage?

Thanks.
