A whiteSpace facet that relaxed its base type's effective whiteSpace was accepted; XSD Part 2 4.3.6 permits only strengthening, ordered preserve < replace < collapse. A base fixed to collapse admits only collapse, and a replace base admits replace or collapse; relaxing it (e.g. replace over a collapse base, or restricting xs:token to replace) is now rejected. The base's effective whiteSpace is its own facet falling back to its built-in intrinsic; the check is atomic-only and, when a base's own whiteSpace has not yet resolved, can only under-detect (an unresolved base defaults to preserve, the weakest), so it never rejects a valid restriction. XSTS: invalid schemas accepted 422 to 413, no other bucket raised.
