 <section1 topic='Approval Process' anchor='approval'>
   <p>The precise mechanism for approval depends on the Approving Body.</p>
   <p>After a XEP has been proposed to the XMPP Council, any change in its status shall be determined by a vote of the XMPP Council. All members of the Council must vote, with the possible values being +1 (approve), 0 (neutral), or -1 (disapprove, with reasons). A XEP shall not be advanced to the next stage in the approval process so long as any Council Member continues to vote -1; that Council Member's written concerns must be addressed in order for the XEP to advance. A majority of Council members must vote +1 in order for a XEP to advance. (Additional voting policies, such as voting periods and defaults if a member does not vote, may be set by the XMPP Council.) A vote of the XMPP Council is final and binding, although a XEP author is free to address the concerns of the Council and to resubmit the XEP for future consideration.</p>
+  <p>If the Approving Body decides after Last Call that the XEP is not ready for advancement yet, but nevertheless useful, it can vote to move it back to Experimental state.</p>
   <p>If the XMPP Council does not complete voting on a XEP before the end of its term, the XMPP Extensions Editor shall issue a new Last Call on the Standards list and the newly-elected Council shall vote anew on the XEP after completion of the Last Call. This provides an opportunity for any member of the previous Council who had voted -1 to voice his or her concerns in a public forum before the new Council votes on the XEP.</p>
   <p>A vote of the XMPP Council applies only to the specific revision of the XEP that has been presented to it. Further revisions may need to be re-submitted for approval.</p>
   <p>Any change in the status of a XEP must be announced on the Standards list by the XMPP Extensions Editor. If a XEP advances to a status of Final, it shall be so announced and also published as one of the official XSF protocols of the XMPP Standards Foundation.</p>
