    The "The 'ippget' Delivery Method for Event Notifications" documents are
    down-loaded. The .txt version is being send to the Internet-Draft editor.
    When it is published as an I-D, Carl-Uno will send it to the IESG. This was
    mainly editorial work: fix the title as noted during the last call and to
    align the presentation with the other Delivery Method documents, plus
    indicate under IANA Considerations:

    The 'ippget' URL scheme for the 'ippget' Delivery Method will be registered
    with IANA according to the procedures of [RFC2717]. According to RFC 2717,
    we have to write a simple RFC in order to register a URL scheme.


    The notification extension document [ipp-ntfy] defines operations that a
    client can perform in order to create Subscription Objects in a Printer and
    carry out other operations on them. A Subscription Object represents a
    Subscription abstraction. The Subscription Object specifies that when one of
    the specified Events occurs, the Printer sends an asynchronous Event
    Notification to the specified Notification Recipient via the specified
    Delivery Method (i.e., protocol).
    The notification extension document [ipp-ntfy] specifies that each Delivery
    Method is defined in another document. This document is one such document,
    and it specifies the 'ippget' delivery method.
    The 'ippget' Delivery Method is a 'pull and push' Delivery Method. That is,
    the Printer saves Event Notification for a period of time and expects the
    Notification Recipient to fetch the Event Notifications (the pull part). The
    Printer continues to send Event Notifications to the Notification Recipient
    as Events occur (the push part) if the client has selected the option to
    wait for additional Event Notifications.
    When a Printer supports this Delivery Method, it holds each Event
    Notification for an amount of time, called the Event Notification Lease
    When a Notification Recipient wants to receive Event Notifications, it
    performs an IPP operation called 'Get-Notifications', which this document
    defines. This operation causes the Printer to return all Event Notifications
    held for the Notification Recipient. If the Notification Recipient has
    selected the option to wait for additional Event Notifications, the Printer
    continues sending Event Notifications to the Notification Recipient as
    additional Events occur.
