Hugo, thanks for your comments.

Re. identifying MEPs by a URI, this has been raised as a LC issue [1] by Glenn
Daniels.

Re. outside references, you may be aware that the XMLP WG is thinking of
publishing an Attachment Note. I expect such a note to cover outside
references. Also, the SOAP Encoding section (Part 2) now uses idref's
(previously href's), to clearly point out references are internal to the
message. Do you think the spec should be more explicit?

Jean-Jacques.
