 Marc, please see my replies inside.

It has been already raised (finally) in my email [1] so I don't
think you need to do anything more on this. 8-)

Yes, I would.

Your wording was "if only one accessor can reference it, an
instance is considered 'single-reference'". What I meant was that
in the data model there is IMHO no instance that _can_ only be
referenced by a single accessor. I see all data as potentially
multi-reference.

To keep your text, I think you need to change it from "can
reference it" to "references it". With such a change, the text
would make sense.

I think the last sentence needs to be reworded, for example
like:

"See section 5 (Using SOAP for RPC) for an example of use of this
data model."

to emphasize that other applications can use this data model and
to clarify the non-normativeness of this reference. I wouldn't
change the preceding sentence in this way, though, to avoid the
impression that people will be welcome if they create forty-two
new encodings for this single data model.

Best regards,
Jacek
