etag values in requests refer to the "selected representation", not the
method specific response.

Basing the selected representation on the method used does not make much
sense imho. 

ETag headers in responses also refer to the selected representation the
response either contains or relates to, and is meant to be able to use
as validator cross methods for the same URI.
