Mihaela Mihaljevic 8e873dc929 fix(schema): an xsi:type must be derived from the declared type (cvc-elt.4.3.2.1); invalid-instances-accepted 133 to 107 (#181) ... First instance-bucket reduction of the campaign. An instance xsi:type naming a complex type must be derived from the element's declared type. notDerivedSubstitutionError flags a complex substitute on a different branch of the hierarchy; previously only a derived-but-blocked substitution was caught (blockedSubstitutionError returns nil when there is no derivation path), so a non-derived xsi:type was silently accepted (the test006 cluster, 32 instances, and more). Conservatively scoped after a broader first cut took 20 false positives (now reverted): it fires only when the substitute resolves to a COMPLEX type and both substitute and declared names are in the derivation backbone with no path between them. Simple/list/union substitutes, ur-types, and unresolvable references are left alone -- under-reject, never over-reject. An adversarial review confirmed the conservative guards eliminate the prior false positives; the one residual is the pre-existing bare-local-name keying of the derivation backbone (shared with blockedSubstitutionError), disclosed in the code, corpus-absent. The three xsi:type override checks (blocked / not-derived / abstract) are folded into one xsiTypeOverrideError helper to keep validateChild under the complexity limit. XSTS: invalid-instances-accepted 133 to 107 (26 caught), valid-instances-rejected and valid-schemas-rejected both held at 0, no other bucket moved.		2026-06-18 10:07:05 +02:00
