+<h3>Information-sharing amongst predisclosure list members</h3>
+<p>Predisclosure list members are allowed to share fixes to embargoed issues,
+analysis, etc., with the security teams of other list members.
+Technical measures must be taken to prevents non-list-member
+organisations, or unauthorised staff in list-member organisations,
+from obtaining the embargoed materials.</p>
+<p>The Xen Project provides the mailing list
+<code>xen-security-issues-discuss@xxxxxxxxxxxxxxxxxxxx</code>
+for this purpose.  List members are encouraged to use it but
+may share with other list members' security teams via other
+channels.</p>
+<p>The <code>-discuss</code> list's distribution is identical to that of the 
primary
+predisclosure list <code>xen-security-issues</code>.  Recipient organisations 
who
+do not wish to receive all of the traffic on -discuss should use
+recipient-side email filtering based on the provided <code>List-Id</code>.</p>
+<p>The <code>-discuss</code> list is moderated by the Xen Project Security 
Team.
+Announcements of private availability of fixed versions, and
+technical messages about embargoed advisories, will be approved.
+Messages dealing with policy matters will be rejected with a
+reference to the Security Team contact address and/or public Xen
+mailing lists.</p>
