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.
