Extending a complexType whose whole content is a non-empty xs:all group, via
complexContent extension that adds element content, nests that all in the
sequence joining base and extension content, which cos-all-limited forbids
(an all group must be the whole content model). Such schemas were accepted.
This is the symmetric companion to the existing rule (an all group in the
extension over a base with content); both now live in one pass. An empty-all
base contributes no content, and an attribute-only extension adds none, so
both stay valid.
XSTS invalid-schemas-accepted 233 to 232, no other bucket moved.
