Qexo is licensed as GPL, but as I understand things with the new build architecture a few mocks ought to take care of things.
Actually this is the only non-issue: Per licensed it under a slightly modified GPL that would allow inclusion in the ASF repo.
The real question is whether anybody out there with programming skill has the time and inclination to make this happen.
I have a strong interest in XQuery, but I don't like that much the kawa solution and I'm really too swamped ATM. But the fact that the SAX support is up to the job now seems like very good news to me.
