v11-03 COMMENT: 18.29 If-Unmodified-Since

I-U-S raises the question, "Which headers must a compliant server
support?" The wording in 18.29 If-Unmodified-Since requires specific
behavior in response to this header that an otherwise compliant server
would violate if it does not implement I-U-S.  (A server that does not
implement I-U-S would return the resource with a 200 (OK) response.)

Some questions, then:
1) Was it the WG's intent to *require* I-U-S support?
2) Should the specification have a list of headers that a compliant
client/server/proxy must support to be compliant?  (Possibly in an
appendix, where it is not normative.)
