Rationale/Explanation of issue:

There are inconsistencies/ambiguities regarding Destination-Host AVP
throughout the document. In older versions (< -05), it actually said that
Destination-Host MUST be present in answers. Is this area missed in the
cleanup process, or??

For example, in Base-07:

In Section 6.1,
"      - a request that is not proxiable (such as CER) MUST NOT contain
        either Destination-Realm or Destination-Host AVPs."
But the ABNF format of CER and CEA listed the Destination-Host as optional.

In Section 6.2, 
"      - The Destination-Host and Destination-Realm AVPs MUST NOT be
        present in the answer message." 
But the ABNF formats of DPA and DWA listed the Destination-Host as
mandatory.

In the three application latest versions, Destination-Host AVP is included
in various Answer messages.

Requested change: 

Cleanup these areas to make it consistent.

Cheers,
Yiwen
