Hi Jim,

About 

> 4.  The query in section 5.1 to a resource directory is not correct.  It would not go to /.well-known/core but to /rd-lookup (or what ever name is used by the RD).   If this is not intended to be an RD query, then the sentence about it above can be omitted.  

> 5.  Please remove the "anchor" target attribute from the response from the RD.  I believe that this is no longer required and it is just adding noise without adding value.  If this is intended to be from well-known then it is sufficient to have the anchor but not to  have the authority section in the href.   </est>;rt="ace.est";anchor="coaps://2001:db8::123]:61617"

The text will now read 
~~~~~~~~~~~
Discoverable port numbers can be returned in the payload An example response payload for non-default CoAPS server port 61617 follows below. Linefeeds were included only for readability.

What do you think? Does it address your two comments 4 and 5?

Rgs,

1.  In section 10.1 the last sentence of the first paragraph and the first sentence of the last paragraph duplicate each other.  This should be cleaned up.

2.  Correct the grammar in the first sentence of section 10.2 -  s/registers a new/registers new/

3.  The correct example DNS name is est-coaps.example.org not
est-coaps.example.ietf.org.   Please correct this.  (See RFC 2606)

4.  The query in section 5.1 to a resource directory is not correct.  It would not go to /.well-known/core but to /rd-lookup (or what ever name is
used by the RD).   If this is not intended to be an RD query, then the
sentence about it above can be omitted.  

5.  Please remove the "anchor" target attribute from the response from the RD.  I believe that this is no longer required and it is just adding noise without adding value.  If this is intended to be from well-known then it is sufficient to have the anchor but not to  have the authority section in the href.  

</est>;rt="ace.est";anchor="coaps://2001:db8::123]:61617"

6.  You have registered 282 and 283 as content types, however you also do not define anything that uses these types.  Either some text about the content types needs to exist or potentially the registrations should be abandoned.

7.  There is an outstanding review from Klaus that needs to be addressed.

8.  There is still an open issue dealing with content types.  I have requested that this be added to the agenda for the next CoRE interim meeting.

Jim
