But RFC2616 is not clear about whether it allows RFC2047-style encoding 
in parameter values. Again, see 
<http://tools.ietf.org/wg/httpbis/trac/ticket/111> and 
<http://greenbytes.de/tech/httpbis/issue-111.xhtml>.

Furthermore, you may have missed the fact that my draft doesn't define 
anything new; it just re-states a subset of RFC2231 (which BTW does 
predate RFC2616), which already is implemented in several UAs.

Turning it around: do you have any evidence of HTTP clients supporting 
RFC2047 encoding in parameter values? If yes, which of the encoding 
methods defined in <http://tools.ietf.org/html/rfc2047#section-4>? With 
what character sets?
