    Here are a few minor comments about
    http://www.ietf.org/internet-drafts/draft-ietf-ipp-url-scheme-00.txt

    Change "Xerox" and "Xerox Corp" to "Xerox Corporation"

    Section 5.2 a implies that an admin cannot configure a printer to accept
    jobs on port 80 and not on port 631. If this is our intention, we should
    explicitly state that a conforming IPP printer MUST NOT allow an
    administration to disable port 631 if other ports can accept IPP jobs. If
    this is not our intention, we should add the "unless explicitly configured
    by system administrators or site policies"

    Here is an issue that probably should be addressed in sections 4.1, 5.1 and
    5.2. The document contains no discussion of what the 'host' and 'path' mean
    in the context of a printer. The reader probably know what it means for an
    HTTP URL, but not what it means for a printer.

    We should probably say that a printer can be identified by a host or a host
    and a path, and that two printers with the same host but different paths are
    intended to be different printers. Here is some suggested text.

    The following are examples of URLs for IPP printers: "ipp://abc.com",
    "ipp://abc.com/printer",
    "ipp://abc.com/tiger","ipp://abc.com/printers/tiger","ipp://abc.com/printers
    /fox","ipp://abc.com/printers/tiger/bob",
    "ipp://abc.com/printers/tiger/ira", "ipp://printer.abc.com",
    "ipp://printers.abc.com/tiger","ipp://printers.abc.com/tiger/bob" and
    "ipp://printers.abc.com/tiger/ira".

    All of the above URLs are legitimate URLs for IPP printers. Each of these
    URLs references a printer which is logically different from the printers
    referenced by any of the other sample URLs, even though some may share the
    same hardware. The last part of the path "bob" or "ira" may represent two
    different hardware devices where "tiger" represents some grouping of
    printers or the two names may represent separate human recipients ("bob" and
    "ira") on the printer named "tiger". In either case both "bob" and "ira" act
    as different printers.
