It has been a while, but when I thought about this I came to the conclusion 
that just one of (context-id) or (stating-id) was sufficient.

E.g. given a (stating-id), (contexts) can be created as RDF containers and 
their contents can be the required collection of (stating-id).

Or, if (context-id) is used, then statements or groups of statements can be 
isolated and referenced by placing them into separate (contexts).
