I don't understand why people would expect GRDDL to do
anything with such schemas.

In what sense should such schemas be considered part of the
meaning of the document?

I don't think I understand what use case you have in mind at all.
Could you elaborate, sort of in story form?

  Bob produces a purchase order document and ...

or

  Linda makes a patient record document and ...

Preferably the story will include at least two parties: one
that produced the document, and one that consumes it, and
it should somehow be clear that the producer has licensed
the data that the consumer gets out of their GRDDL agent, per
the "Faithful Renditions" section.
