RDDL makes it easy to list half a dozen different schemas (in multiple schema languages or even in just one) for a namespace - the "purpose" and the human- readable documentation would ideally explain the differences between them and what they're intended to be used for. A RDDL could have pointers to two wildly-different XML Schemas with identical natures and purposes, both claiming to be the only authoritative way to validate elements from some namespace - in which case it would hopefully supply some additional human-readable documentation to help sort things out. The fallacy that there can be a single right schema or stylesheet or whatever is probably the central motivation that drove me into the work of helping with RDDL. I don't think you've established that goal #3 is not achievable in the general case. In the face of lousy hodge-podge designs that pay little attention to composability, obviously pointers to the relevant bits of schema-ware and so on aren't going to help. But we can hope for better than that. -Tim
