I think this would be a better long-term solution. substitutionGroups are a safer way of managing inheritance which do not require the document instance to "carry" the type information all the time. One question someone might be able to clear up for me. If you create abstract elements whose models are based on other abstract elements are you creating multiple inheritances or not? (In ebXML we are using abstract classes to define sharable components which themselves contain embedded sharable components.) Martin Bryan
