I do not have any problem in formulating the requirements like you have
stated, but I have a couple of questions:
1) Are there any URI schemes that do NOT allow you to specify a port number
as part of the URI (just a wording question)?
2) I hope that we are not in conflict with the HTTP 1.1 spec if we allow an
HTTP server, providing IPP service, NOT to support the HTTP default port 80.
A couple of quotes from RFC 2068:
"The default port is 80, but other ports can be used."
"If the port (in the URI) is empty or not given, port 80 is assumed."
This seems to indicate that an HTTP 1.1 server MAY be allowed to ONLY
listen to another port number, which I believe was the new part of Randy's
