The top-level declaration constraints (a global element/attribute may not carry
the local-only form/use/ref/minOccurs/maxOccurs; a global definition needs a
name) apply to every document in a schema composition, but the existing check
ran only over the document being compiled. A violation inside an xs:include,
xs:import, or xs:redefine target was therefore missed and the composed schema
wrongly accepted. The same global-component check now runs over the other
schema-document roots in the composition (the main document is excluded as
already covered; redefine entries are skipped because each schema root walks its
own redefine children). The constraint is absolute and position-independent, so
no valid schema is newly rejected; libxml2 rejects both cases for the same
reason. Catches attQ016 (import) and attQ018 (include). XSTS invalid-schemas-
accepted 20 to 18, valid-schemas-rejected held at 0.
