I like where this is going - but it changes 'a plea for schemas' to 'a plea for a discovery mechanism for information about XML documents'. I think you've got the right idea here, a way to keep the open approach of the BizTalk schema repository without the baggage of the BizTalk framework and its owners. Instead of the centrally adjudicated process, we get an open system for describing information that can be distributed rather than centralized. I'd like to think the W3C's new XML Packaging approach will provide some tools for this, though it's too early to see where it's going. >This idea has been derided by some because it smacks of AI technologies >that have been heavily hyped and then failed to materialize in the past. >But a simple full-text search could be very effective on this volume of >data.

I'm not even concerned about 'weeding out the junk' - I'm more concerned that everyone who writes a schema or even a textual description of a document structure has a means to publish that information. If aggregators wants to provide rating services on top of that, but it's more important to me that I be able to do things like: <memo xmlns="mailto:simonstl@s..."> <to>You!</to> <from>Me!</from> <contents>Hi there!</contents> </memo> and have some way for recipients of this message to process/transform it into their own preferred memo format without requiring them necessarily to contact me about it.
