Sinossi

High Quality Content by WIKIPEDIA articles! The Unique Particle Attribution (UPA) rule is XML Schema's mechanism to prevent schema ambiguity. Due to the UPA rule the schema fragment given below is prohibited. It is not possible to create a Post-Schema-Validation Infoset, because it is ambiguous whether should be associated with the element declaration x, or the wildcard (xsd:any). The W3C schema workgroup is considering weak wildcards for schema version 1.1. Using weak wildcards, the explicit element declaration would always take precedence ( is associated with the element declaration), thus removing the ambiguity.
