Thanks Michael.  Could you point me to some documentation that explains how
to build a TinyTree from a file, and how to create a Source object out of it
(and which Source implementation to use)?  I am not really familiar with
Saxon's own API, as I've always used it through JAXP interfaces.

Also, I am somewhat reluctant to indroduce a direct dependency on Saxon in
my code (although I suppose since I am using some XSLT 2.0 features, I
already have it, whether I want it or not. :)  Could you provide some more
insight as to what advantages a TinyTree provides over a simple byte array
in my situation?  Is it significantly less expensive to create a Source
object from a TinyTree than from a byte array?

Thanks again.
