Unfortunately, this conflicts with the desire to use UTF-8 in attribute
values - RFC 822 (and also 2822) don't support this, but require the
use oF MIME instead (Q or B encoding).

RFC 2822 also has a continuation line semantics which traditionally 
conflicts with the metadata; in particular, line breaks cannot be 
represented (but are interpreted as continuation lines instead).
OTOH, several of the metadata fields do require line breaks, in
particular those formatted as ReST.
