Hi, Yingjie,

I have some comments on the XML expression as follows:

section 5.1.1
It's ok that one example is presented to show the format of the shared mesage body. But it seems as the content emeded in the message body, having no relation with the "Common Message XML Header", so my advice is to modify the figure title.

section 5.1.2.1
The example for the peerlist representation is not the formal XML format. It can be expressed as follows:
      <Peers>
          <Peer1>
              <PeerID> 48482345122344 </PeerID>
              <PeerAdd> 193.2.2.4 </PeerAdd> 
          </Peer1>
          ... ...
      </Peers>

section 5.1.4.2
The example shown for the FIND response message is just XML schema, rather than message instance. So maybe the figure title should be changed to "XML schema expression for FIND Response message". The same problem exists in the following figures from Figure 6 to Figure 11.

Welcome for more discussion.

主题： [ppsp] Please review the updated Tracker protocol

Hi all,
We have uploaded a new version of Tracker protocol. You can find it under PPSP documents webpage, or http://www.ietf.org/id/draft-gu-ppsp-tracker-protocol-05.txt
In this version, we make many changes according to the meeting minutes. 
First of all, we optimize the message definiti on, make optional. We provide more flexibility to implementation, which can help to decrease rounds of message communication and increase efficiency. An example flow is provided, together with example encoding.
Secondly, we update syntax. At last meeting, Wes raised that it was not valid http-xml based encoding. We make large amount of revision to the encoding to make it look better. Hope you can help us to improve it.
 
There will be a virtual interim meeting at this Wednesday. Please try to review it before the meeting if convenient. 
Thanks a lot.
 



Best Regards
Gu Yingjie
