Hi Steve,

I think the draft is in pretty good shape, but I have a few comments 
(mostly nits) and I did get confused in Section 5.1.2 --

Minor issues:

Section 5.1.1

   "When relaying a request that includes a SourceID AVP in the OC-
    Supported-Features AVP, a DOIC node that supuports the OC_PEER_REPORT
    feature must remove the received SourceID AVP and replace it with a
    SourceID AVP containing its own Diameter identity."

Shouldn't "must" be "MUST"?

Section 5.1.2

   "When relaying an answer message, a reporting node that supports the
    OC_PEER_REPORT feature MUST strip any SourceID AVP from the OC-
    Supported-Features AVP."

And replace it with a SourceID AVP containing its own Diameter identity? 
Or does an answer with an OC-Supported-Features AVP that does not have a 
SourceID AVP mean the peer is an agent? Section 5 doesn't cover how to 
interpret an OC-Supported-Features AVP without a SourceID, only when a 
SourceID doesn't match the peer.

Section 5.1.2

   "If the peer supports the OC_PEER_REPORT feature then the reporting
    node MUST indicate support for the feature in the Supported-Features

Should be "OC-Supported-Features".

Section 6.1

Should the AVP Code for OC-Supported-Features be 621 instead of TBD1? (I 
wasn't sure if, when extending an AVP of type Grouped, you needed to 
give the AVP a new AVP Code, and I couldn't find guidance in RFC 6733 or 
RFC 7423) Also, AVP Code TBD1 is used for OC-Peer-Algo AVP in Section 
6.1.2 and for SourceID in Section 6.4. TBD2 is used for OC-OLR in 6.2 
(should it be 623?), SourceID in 6.3, and OC-Peer-Algo in 6.4.

Section 6.2

   "The overload report must also include the Diameter identity of the
    agent that generated the report."

Shouldn't "must" be "MUST"?


Section 3 - s/"suited controlling traffic"/"suited to controlling traffic"

Section 5.2.4 - s/"reporting nodes transaction state"/"reporting node's 
transaction state"

Section 6.1 - s/"handling by the agents peer."/"handling by the agent's 

Section 6.1.2 - s/"reused in for this AVP."/"reused for this AVP."

Section 6.2 - s/non supporting/non-supporting
