I posted the following comment to the list on 10-Jan-2002:

 This document should make it clear that it updates RFC 2910.

 This document repeatedly says that both RFC 2373 and RFC 2732 update
 RFC 2396, but only RFC 2732 actually does this. As such, only RFC 2732
 should be listed.

 Section 4.1 should make it clear that this URL scheme is used to designate
 entities that implement the IPP protocol rather than being used as an IPP
 protocol element.

 The same paragraph occurs 4 times in the document: the first
 2/3 of the abstract, and in section 1, 4.5, and 6. Repeating something in
the
 in the document proper, but the other repetitions should be eliminated.

 There are no examples of URLs referring to jobs, only several examples of
URLs
 referring to printers.  Jobs seem like a much more interesting use of ipp
URLs,
 especially returned in the job-uri: response to a job submission, so
examples
 of them should be included if possible.

 The second paragraph of section 4.5 appears to be a repeat of section 4.1,
and
 should be removed.

 The title of section 4.5 is "IPP URL Scheme Syntax in ABNF" but the section
 includes a lot of material besides the ABNF. "IPP URL Scheme Syntax" might
 be a better title.

 The second paragraph of section 4.5.1 uses the term "may represent" in a
couple
 of places. This makes it sound like (a) These are the only possible
functions
 of the last element of a URL and (b) Only the last element of the URL can
 perform these functions. One possible way to make this clearer would be to
say
 "might represent" rather than "may represent".

 Section 4.5.1 includes several examples of IPv6 URLs near the end. It is
 intended that explicit IPv6 URLs will only be used in emergencies, so it
isn't
 appropriate to include such examples in this document.

 Security considerations for URL schemes may be different than security
 considerations for the protocols that the URL schemes designate. There are
a
 set of questions associated with URL schemes in section 2.4 of RFC 2718
that
 should be answered in this document.

As far as I can tell you haven't addressed a bunch of these.
