I've suggested that the entire descriptive type system and the PSVI it
seems to expect on the other end is broken.
Regular Fragmentations suggests a rather different processing model.
You still could have simple types and facets for the fragments, but
they'd have a lot fewer parts and require less understanding than the
Datatypes spec currently offers.
I'll be talking more about this at XML 2001, and hope to have more to
show by then. My presentation from the Extreme Markup Language
conference  covers some of it.
