Hi Mike,

I have read both documents. In context of this discussion the question
is whether we

(a) require them to be read (in which case they should be a normative
reference), or
(b) suggest them to be read (since they provide additional background
information). In this case they are an informative reference.

I believe believe we want (b) for the OAuth WG document. While I
encourage everyone to read the publications I also believe that there is
lots of material in there that goes beyond the information our audience
typically reads (such as the text about the formal analysis).

There is probably also a middle-ground where we either copy relevant
text from the papers into the draft or reference specific sections that
are "must-read".

One other issue: I actually thought that the threat that is outlined in
the research paper is sufficiently well described but the second threat,
which is called 'cut-and-paste attack', requires more work.
I noted this in my summary mail to the list, see
http://www.ietf.org/mail-archive/web/oauth/current/msg15697.html

Ciao
Hannes
