    Surendra,

    I have looked through your recent Internet-Draft
    <draft-skreddy-enp-protocol-00.txt> on notifications.

    Although you seem to have aligned your proposal mostly with the WebDAV
    solution, you also mention that it could potentially be used also for the
    Internet Printing Protocol (IPP).

    As you might be aware we have struggled with the definition of Notifications
    for IPP for more than a year in the IPP WG and are close to wrapping up the
    subject.

    You may want to take a look at our latest I-Ds on Notifications in IPP.

    They are:

    IPP Event Notification Specification
    <draft-ietf-ipp-not-spec-02.txt>

    which describes the overall model and what we call the subscription part of
    the notification mechanism.

    We have also designed several alternative methods for the delivery of
    notifications. The method closest to your proposed protocol can be found in
    the following two drafts:

    IPP Notification Delivery Protocol (INDP)
    <draft-ietf-ipp-indp-00.txt>

    The INDP Notification Delivery Method
    <draft-ietf-ipp-indp-method-00.txt>

    Note that these documents are currently being revised, but they should still
    give you a sense for the direction in which we are moving.

    We would be interested in getting your comments about how far apart you
    think we are. There are some obvious differences at present, such as our
    subscription mechanism, which might be unique to IPP, and the fact that you
    are using XML, while we are not.

    I think that if you want to make a claim that your solution could cover IPP
    as well as WebDAV, there are probably a few things missing from your
    solution. As we provide for a number of different notification delivery
    methods, I would expect that it could be easier to reach some level of
    commonality in that area.
