This has nothing to do with ur-schema.
I simply took our actual 0p70 (that does _not_ embody the ur-schema concepts) and I did a simple extension using XSD derivation.
A question arose during the latest local/global discussions.
(We're considering adding to the SC charter, a clause requiring all meetings to begin and end with such a discussion -- kind of like the prayer in Congress or the Pledge of Allegiance in first-grade)
Anyway, the concern was that perhaps now that we're using global elements, then the expected sort of subtyping wouldn't work.
The example proves the concern unfounded -- subtyping works just fine.
So I'd say this is just an example of "manual extension" of 0p70.
And that's good in itself I guess.
