Well xquilla on top of xerces should get us pretty much were we need to 
go. They are both under the Apache 2 license, which I believe would be 
ok. But they are C++ so I don't know if we could use them.

I found Zorba, its C++ and Apache 2. But I don't know much about it. But 
it looks promising.

Sedna is a complete db/xquery solution licensed under Apache 2 and 
written in C/C++. Perhaps we could use pieces of this. Better than 
starting from scratch.
