Hi, Please could someone clarify whether the pattern facet is applies to list datatypes. In Section 2.5.1.2 List datatypes, it states: "When a datatype is ·derived· from a ·list· datatype, the following ·constraining facet·s apply: * ·length· * ·maxLength· * ·minLength· * ·enumeration· * ·pattern· * ·whiteSpace·" http://www.w3.org/TR/xmlschema-2/#atomic-vs-list However, in the description of the built-in list data types, xs:NMTOKENS, xs:IDREFS and xs:ENTITIES, the lists of constraining facets does not include the pattern facet. Should we conclude from this that xs:NMTOKENS, xs:IDREFS and xs:ENTITIES are exceptions to the general rule about list data types, or is this an error in the Rec.? If the latter, is it that the pattern facet does not apply to list datatypes, or that it does apply to those three list datatypes? Thanks, Jeni --- Jeni Tennison http://www.jenitennison.com/
