MS> I'm not sure what benefit this will add - if you have multiple
    subscriptions, you probably will either have a common recipient
    URI or the subscription IDs themselves, so why would support for
    both be needed?

<ira> Marty describes the following scenario.  A Notification
Recipient (NOT the job originator, maybe your secretary)
issues Get-Subscriptions with a known "notify-recipient-uri"
(e.g., your secretary's 'mailto:' address in 'ippget:' form).
Subsequently this Notification Recipient issues periodic
(polling) Get-Notifications with the explicit list, but wants
to ALSO find any new subscriptions.

<ira> I'm not entirely sure I like this optimization.  At any
point, this Notification Recipient can re-issue Get-Subscriptions
and do the search.  Adding the optional search (even when the
"notify-subscription-ids" operation attribute is supplied) seems
like a questionable optimization to me.  I think this kind of
"third-party" Notification Recipient (not the job originator)
should probably do periodic Get-Subscription operations anyway.
