Looks good to me. At the end of the day, please go ahead ab request publication of the updated draft. I'll then notify ted that this draft has been modified to address the IESG comments.

   Another environment where efficient and meaningful notification using
   OPES tracing is possible are Content Delivery Networks (CDNs).  A CDN
   node may use multiple content adaptation services to customize
   generic content supplied by the content producer (a web site). For
   example, the node may insert advertisements for client-local events
   or services.  The node itself may not understand specifics of the ad
   insertion algorithm implemented in OPES callout servers.  However, it
   may use OPES trace to notify content producer about the number of
   certain advertisements inserted (i.e., the number of "impressions"
   delivered to the customer) or even the number of ad "clicks" the
   customer made (e.g., if the node hosts content linked from the ads).
   OPES services doing ad insertion may lack details (e.g., a customer
   ID/address or a web server authentication token) to contact the
   content producer directly in this case.

Just for clarification - this example implies that an OPES processor could use trace information to determine where to send notifications to. The destination of such notifications could be either the content producer or another (upstream) OPES processor. In the former case, there would be an OPES trace entry for the content producer?

Thanks,
