The Jinks build should now fail on finding any duplicate @xml:id attributes. I've also been working on the static build for AJAX components, and realizing that I have to backtrack a bit and reconsider how fragments are processed; it's quite a gnarly thing, since they have to be wrapped (for AJAX purposes) and yet they have to have the same @xml:id, so that attribute has to sort of migrate up the tree in a way that makes me a little uncomfortable. I have people and orgs building too (although I've broken that somehow in the last hour).
