The new text from Juergen is fine, now that Martin pointed
out that the text cannot possibly be interpreted to mean
multiple subscriptions on 1 session.

I think the new text suggests the opposite, but the text in 6.5
clearly says otherwise (in case it comes up in the future that
the standard is ambiguous wrt/ multiple subscriptions per session).
