I do agree that if we can't make progress, we should defer. That being 
said, I think the discussion so far was very useful, if only in helping 
to understand the problem.

Also, this issue affects another issue I'd like to really make progress 
on (the BNF->ABNF switch). Is there a chance that we can decide on which 
headers currently *do* allow RFC2047 notation?

Two more thoughts:

1) Do we have *any* evidence of HTTP servers actually using RFC2047 
encoding, or clients being able to decipher it?

2) I'll also have to point out that given the state of things with HTTP 
header I18N we observe, the WebDAV WG's decision to put metadata into 
XML was absolutely a good one.
