I suggest you want to know, how to define the restriction for some XSD Schema? As far as I know for that case you have to define your own type, which might look like this (untested): <xs:simpleType name="myRestrictedType"> <xs:restriction base="xs:string"> <xs:pattern value="([a-zA-Z]|[0-9])"/> </xs:restriction> </xs:simpleType> and reference from your attribute declaration: <xs:attribute name="type" type="myRestrictedType" use="required" /> Hope that helps! -- Dennis Sterzenbach
