Mihaela Mihaljevic b3a2bcfe6a fix(schema): flag a baseless or ancestor complex xsi:type as not derived; invalid-instances-accepted 60 to 53 (#181, #147) ... A complex type that records no base of its own derives only from xsd:anyType, so it cannot validly substitute (cvc-elt.4.3.2.1) for an element whose declared type is a more specific complex type. The not-derived check required the substitute to be present in the derivation backbone, so naming the declared type's own complex ancestor, or an unrelated baseless complex type, via xsi:type was accepted. notDerivedSubstitutionError now treats a complex substitute as in scope even when it is absent from the backbone: its non-derivation from a non-ur declared type is certain (a baseless complex type derives only from anyType, and any real extension/restriction chain is recorded in the backbone, where derivationMethods finds it). An atomic substitute must still be in the backbone, so a built-in stays silent. The declared guard excludes the ur-types, so a baseless complex substitute under an anyType declaration is admitted; a genuine extension or restriction substitute is accepted. invalid-instances-accepted 60 to 53, no false positive (valid-instances-rejected and valid-schemas-rejected held at 0), no other bucket moved. An adversarial review exercised deep, cross-namespace, redefine, and element-ref-path derivation chains plus anyType-declared baseless substitutes, and found no over-rejection.		2026-06-18 13:51:17 +02:00
