I'm having exactly the same problem. I've been looking at the documentation 
for complexContent and complexType but haven't figured out how to get the XML 
editor to allow me to enter the inherited elements. Its kind of amusing since 
I have a key constraint that requires the field, so I get one error that its 
missing, then if I add it I get another error that its present. Kewl.
