So, once again I am proven wrong, and I am actually happy! I totally forgot that I included a template to import another xml document. I now have two concerns:

1) Why was there not a more descriptive error; I didn't even see anything indicative of an error during import when I turned the debug switch on.

2) How do I include multiple sources into the transformation process? If I am unable to do that, things are going to get very complicated, so much so that I'm going to have to seriously rethink going back to good 'ol perl interposed with html.

Thanks for all the help rg0now, I probably would've thrown in the towel without your analysis.
