The problem is in the above element declaration and the problem is that you have used a simpleType as the base type in a complexType definition derived by restriction which is not valid. Instead you need to extend the simpleType xs:string by adding an attribute. So, change <xs:restriction> to <xs:extension> and everything should work fine. Cheers, /Eddie
