A simpleContent restriction is (annotation?, (simpleType?, facet*), (attribute|attributeGroup)*, anyAttribute?) and an extension is (annotation?, (attribute|attributeGroup)*, anyAttribute?): no model group, no facets/simpleType in an extension, attributes before a single anyAttribute. The membership table admitted the names but not the order or the model-group ban, so a model group inside simpleContent, a facet in an extension, a misordered facet or attribute, or a second anyAttribute (the ctD family) was accepted. The derivation's children are matched against the context's ordered slot model, reusing the slot walk built for complexContent. The structure walk's per-component dispatch is factored into a helper to keep its complexity bounded. XSTS: invalid schemas accepted 594 to 580, valid schemas rejected held at 72, instance buckets unchanged.
