For right now, rather than moving up to a more abstract model, I'm trying to stick with the extremely concrete world of elements and attributes as they presently exist, atomized and disjointed as they may seem. I think most of the dreams that people have brought up in this discussion, including the one above, are eminently achievable. The key is building referenceable and extensible structures. XSchema 1.0, so far, seems very usable in this regard, though not especially elegant. (The concrete world weighs heavily.) The reason this less-than-100%-elegant exercise is valuable, in my mind at least, is that we're providing schemas in a form that can be easily referenced (through XPointers, mostly) and extended. Simply tagging elements in a way that they can be referenced opens the way for future work in inheritance, extension, and different means for specifying constraints and content. I'd like XSchema to provide a foundation for all that; so far it seems like we've got a good shot at it.
