Not really a bug, but a feature -- because the base is strict, and
there are no elt declarations in the schema, that wildcard accepts
nothing.
So the base, which does accept something, can't be a restriction of
it.
Remember (:-) that XSV already implements the expected Schema 1.1
approach of restriction as subsumption/subset pretty much literally,
and this is one of the few cases where that bites.
