Extending the new positive double simpleType into a simpleContent. > Thanks, Pete: After thinking about this I decided that it would also be good to have an AreaType and a LengthType, etc., which will be helpful shorthand in the remainder of the schema. So, with your suggestions above, this becomes: <!-- Global Types for this file --> <xs:simpleType name="AreaType"> <xs:restriction base="xs:string"> <xs:enumeration value="M2"/> <xs:enumeration value="FT2"/> </xs:restriction> </xs:simpleType> <xs:simpleType name="PositiveNumber"> <xs:restriction base="xs:double"> <xs:minExclusive value="0"/> </xs:restriction> </xs:simpleType> <!-- Wing Area --> <xs:element name="wingarea"> <xs:complexType> <xs:simpleContent> <xs:extension base="PositiveNumber"> <xs:attribute name="unit" use="optional" default="FT2" type="AreaType"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> The above definition worked well, and the documentation was produced correctly in oXygenXML, which also validated the following XML: <wingarea unit="FT2"> 174.0 </wingarea> Thanks for your help. This is fun stuff, but sometimes frustrating. Jon Project Coordinator, JSBSim Flight Dynamics Model Project www.jsbsim.org
