    Hi Michael,

    Wait - the IETF _will not_ allow 'ippget:' (with nothing following or
    with nonsense that isn't a protocol target address following) as a
    URL scheme. It violates all the rules of URLs usage.

    The idea is that the EMPTY string (not the 'ippget' value) is
    unambiguous. BECAUSE it's empty there is NOT a protocol target for
    the IPP Printer object to send notifications to. The IPP client
    must retrieve the notifications in-band via IPP.

    OK?

    Cheers,
    - Ira McDonald

    Assuming that the IETF allows "ippget" as a scheme name, then
    allowing "ippget" as the only allowed notify-recipient-uri should
    also be OK (and perhaps less confusing than passing in a 0-length
    string which might trigger other parsing errors since some IPP
    implementations might validate URI values as valid URIs... :)
