Heh, I suppose I could have run it through a validator first!  Not to  
difficult to fix at least.

This was a tricky thing.  I was testing the XSLT transformations with  
Firefox, and oddly, it refuses to load them for application/rdf+xml,  
but has no problem with application/xml.

Latter is a bit odd, former is something I'm aware of and still  
working on (need to thread all of the category searches together to  
make sure that the response is either unique, or not, depending on

Thanks for the help.  I'll definately go back and fix these.  Even I  
admit that it's still a bit buggy and under development, but it's  
always good to have someone to remind me what I'm missing.
