Mihaela Mihaljevic 6147666e49 feat(schema): structural validity against the schema-for-schemas content model 
The general mechanism for the structural tail of the schema-validity gap, in
place of hand-coding a rule per component. A data-driven table encodes the XSD
1.0 schema-for-schemas child content model; at compile time it rejects any
component child the model does not admit, more than one annotation (or an
annotation that is not first, except on schema/redefine, which allow several),
and an identity constraint missing its selector or field.

The walk visits only XSD-namespace elements and skips appinfo/documentation
foreign content, so foreign children are never flagged; restriction/extension
use the permissive union of their simple/complex/simpleContent contexts, so a
child valid in some context is never rejected. One table covers every component.

XSTS: invalid schemas accepted 1688 to 1313 (-375); valid schemas rejected held
at 72 (no over-rejection); instance buckets unchanged.
