In line with our new procedures, I'd like to ask the IESG for consensus on asking the IAB an architectural question related to draft-klensin-name-filters-03.txt, which has been sent to the RFC editor for publication and referred to us for review as an Informational RFC. The draft raises an issue related to protocol processing which seems to me fairly important, which I would summarize as: "What issues should be considered when deciding when and how to apply validity checks for protocol processing not conducted by the application applying the validity check?"
To steal a concrete example, what might be the issues in an application pre-checking the syntactical validity of a DNS name prior to passing it to the DNS?
If I understand the next steps correctly, once the IESG has come to consensus on the question, Harald would send the question to the IAB, along with a description of what we expect in response. I would expect two things in response: a review of the Klensin draft and a short document describing the issues. Note that this is not asking them to re-write the Klensin draft, which explicitly does not take on this task:
"this document takes no position on whether or not the testing is desirable. It only identifies the correct tests to be made if tests are to be applied."
regards, Ted Hardie
