Re: [regext] [Ext] I-D Action: draft-ietf-regext-epp-ttl-06.txt

Hi Jim,

Thanks for the feedback, I've incorporated your suggestions into my working draft and they will appear in the next version.

The EPP <info> command is extended to support two different modes: the Default Mode (Section 2.1.1.1) and the Policy Mode (section 2.1.1.2).  The Default Mode requests the inclusion of all non-default TTL values in the response. The Policy Mode requests the inclusion of TTL information for all supported DNS record types in the response, with the minimum value, default value, and maximum value.

If a server receives an <info> command for a domain or host object which includes a <ttl:info> element with a “policy” attribute value of “0” or “false”, the EPP <response> MUST contain an <extension> <ttl:infData> element containing <ttl:ttl> records for all that DNS record types that have non-default TTL values.  The <ttl:ttl> elements MUST NOT have the “min”, “default”, and “max” elements.

I believe it’s best to make it clear that the Default Mode must not include the policy elements.  I don’t believe there is the need to define the exclusion of the “policy” attribute, since the default value of “false” will cover the absence use case.

If a server receives an <info> command for a domain or host object which includes a <ttl:info> element with a “policy” attribute value of “1” or “true”, the EPP <response> MUST contain an <extension> <ttl:infData> element containing <ttl:ttl> records for all supported DNS record types, irrespective of whether those record types are in use by the object.  The <ttl:ttl> elements MUST have the “min”, “default”, and “max” elements.
