The interpretation of the first node must be a property and have an appropriate property extension. That node may be the same as the list node, or could be some other node, that depends on the mapping rules. > > Is this a correct summary of the problem?

I wasn't trying to restrict myself particularly. I think it is poor form to sit on issues and raise them later in the working group life, when I am aware of them today. Jeremy
