XSD 1.0 gives a named model-group definition's content as
(annotation?, (all | choice | sequence)) -- exactly one compositor. The
allowedChildren set-membership check allowed any number, so an xs:group with two
compositors, or with none, was accepted. namedGroupErrors now enforces the
cardinality, gated on the node being a definition (has a name) so a group
reference is never flagged.
XSTS: invalid schemas accepted 977 to 956 (-21); valid schemas rejected held at
72; instance buckets unchanged.
