I have now got a response from Keith Moore on our earlier question about
referencing IPP1.0 in the IPP/1.1 document. See his thoughts below.
When he mentions "Last Call" I believe he means the IETF wide Last Call
which is issued by the IESG after we have given them the documents.
Also, it now looks unclear whether Keith will be able to dial in to
our meeting in Philadelphia - please stay tuned.

sorry, I thought I answered this.
in general, we cannot have a normative reference from the 1.1 specification
to the 1.0 specification.
an alternative would be to incorporate the relevant parts of the 1.0
specification into the 1.1 specification, say as an appendix.
another alternative would be to request a variance from the normal rule
forbidding normative reference to informational/experimental specifications.
we might be able to do this on the same Last Call as for IPP 1.1.
either way, the biggest trick is probably authentication - if you require
implementations to support 1.0 then they will have to be able to either
disable 1.0 support, or support the same authentication methods for 1.0
that they do for 1.1. (in other words, we can't open up a security
hole by requiring support for 1.0)
p.s. I have just found out that I need to be in DC on May 27, so I don't
know whether I'll be able to join the Philadelphia meeting by telephone.
Will let you know what works out.
