Re: Issue #170: "Referencing Data missing from the message"

+1

This was what I was proposing at the last f2f, that
the encoding should be restricted to ID/IDREF within the
envelope (XML) document. Any external references are
(application) data (e.g. an anyURI type element information
item).

Cheers,
