A top-level xs:element declaration (a direct child of schema, or of redefine) was accepted with ref, form, minOccurs, or maxOccurs. A global element is a declaration, never a particle or a reference, so those local-use attributes are prohibited by the schema-for-schemas topLevelElement. The top-level-attribute applicability scan is generalized into topLevelDeclarationErrors, driven by a per-kind forbidden-attribute map, covering both attribute and element. A local element particle inside a content model is unaffected. XSTS: invalid schemas accepted 424 to 422, no other bucket raised.
