Furthermore, a correct value may not exist. template - the value will be available later unknown - The correct value is not known to, and not computable by, the sender of this data. However, a correct value probably exists. withheld - the value is not divulged other:reason - as indicated by "reason" string Specific communities may agree to assign more strict semantics when these terms are used in a particular context. </xs:documentation> </xs:annotation> <xs:union> <xs:simpleType> <xs:restriction base="string"> <xs:enumeration value="inapplicable"/> <xs:enumeration value="missing"/> <xs:enumeration value="template"/> <xs:enumeration value="unknown"/> <xs:enumeration value="withheld"/> </xs:restriction> </xs:simpleType> <xs:simpleType> <xs:restriction base="string"> <xs:pattern value="other:\w{2,}"/> </xs:restriction> </xs:simpleType> </xs:union> </xs:simpleType> |
