An xs:element or xs:attribute declaration carrying both a default and a fixed value constraint was accepted; XSD 1.0 src-element.1 / src-attribute.1 make the two mutually exclusive. The check rides the existing value-constraint structure walk, gated to XSD-namespace declarations and reading the unprefixed default/fixed (a foreign same-local-name attribute is not the value constraint). It is per declaration, so a default on a global declaration and a fixed on a reference to it (two separate items) remains valid. XSTS: invalid schemas accepted 479 to 469, no other bucket raised.
