Hi, just a question inbetween: The example from ht was: <xs:complexType name="t1"> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute name="x" type="xs:integer"/> </xs:extension> </xs:simpleContent> </xs:complexType> <xs:complexType name="t4"> <xs:simpleContent> <xs:restriction base="t1" > <xs:simpleType> <xs:restriction base="xs:token"> <xs:pattern value=".*a.*"/> </xs:restriction> </xs:simpleType> </xs:restriction> </xs:simpleContent> </xs:complexType> So what does type t4 expresses? Is it: - t4 permits the attribute with name "x" (as inherited from t1) - The content of t4 can be of type xs:token and has to match the pattern. Is this a valid restriction to the base of t1, because token restricts string and pattern is a valid restriction of the value space? Am I correct? What confuses me is the local usage of the simpleType and the introduction of a new base type. Thanks, Harald
