An element ref carrying nillable/default/fixed/form/block, or an element or attribute ref carrying an inline type definition, was accepted. A ref is a use of a global declaration, not a declaration, so beyond ref it admits only minOccurs, maxOccurs, and id (src-element.2.2). The applicability check already excluded name and type from a ref; this extends the exclusion to the remaining declaration-only properties and to an inline simpleType/complexType child. minOccurs/maxOccurs, a group/attributeGroup ref, and an attribute ref's use/default/fixed (which override on the use) are unaffected. XSTS: invalid schemas accepted 439 to 424, no other bucket raised. Disclosed under-detection: a key/unique/keyref child under a ref is not yet flagged.
