Thanks for the info. How "standard" are extension functions? I am using
Xalan, so is the use if evaluate going to tie me to Xalan?

The business case is that we have 3 documents, which have the same
equivilant structure but different node names. So <parent><child> is
essentialy equal to <p><c>. We can not pre-process the data to first
transform <p><c> into <parent><child>. So, we hoped to have an intermediate
template call the final template with the path to the data.
