Hi, all, Is there any way to require that some attributes must to occur together? I have an element "Get" the semantics of which and therefore the attributes required depend on the attribute ("source"). I created attributeGroups each with another fixed value for the required "source" attribute, but unfortunately one cannot embed attributeGroups in <choice> elements or some other representation with "or" semantics. I then created a complexType with each of the attributeGroups and a group like that <group name="SomeGetElement"> <choice> <element name="Get" type="GetType1"/> <element name="Get" type="GetType2"/> <element name="Get" type="GetType3"/> <choice> </group> but got an Error because of a "Unique Particle Attribution" violation. I don't want to specify "xsi:type" in the instance document, but is there any way out without breaking up my "Get" element into multiple elements? Thanks an advance, Sonja
