Somebody else pointed out in the meantime that the same question applies 
to Last-Modified.

Anyway, if this is what everybody agrees upon, this IMHO should be put 
into the RFC2616 errata.

Also, it means that an ETag obtained from a PUT response can not be used 
as validator in byte-range operations, right? That may come as a 
surprise to some ;-)
