Re: [regext] [Ext] I-D Action: draft-ietf-regext-epp-ttl-05.txt

[Gavin Brown <[e-mail]>]

Hi Jim,

Thanks for this feedback.

Am I correct in saying that in your view, if a server receives an unextended <info> command (on a session where the TTL extension was included in an <extURI> element in the <login> frame) then the <info> response should not include the <ttl:infData> element in the response?

If that's the case, then this seems somewhat at variance with the approach taken historically: for example, one does not need to extend the <info> command to get the <secDNS:infData> and <rgp:infData> elements in the <info> response.

Are there examples of more recent extensions which require an extension to an <info> command to get an extended <info> response? I would not consider the launch extensions here for example, since it requires the client to provide parameters in order to satisfy the request.

Thanks,

Gavin.

I did find one issue with the XML schema, where <attribute name="policy" type="boolean" required="true"/> needs to be <attribute name="policy" type="boolean" use="required"/>.  I would prefer making the "policy" attribute optional with a default value of "false", as in:
