The example does not map to the current CC Party description because that
was not available to us when the example was done. Hemce thing like
PartyIdenfication are not included.

If you specify no changes to the subcomponents using the CreateGroup or
UseElement elements then the existing model for the referenced element is
presumed to be used without change.

The text needs a lot of clarification: this is one.

Good question. My personal feeling is that this is an error situation,
unless there are no UseElements so that the exsiting model is retained.

The implication is that it is, but this is not specifically stated.
(CreateGroup definitely requires the recursive use of CreateElement or
UseElement, and as these can contain CreateGroup I presume you have the same
infinite recursion levels that any XML data model has.)

None whatsoever, much to my chagrin.
