Things which are at the top of my hit-list are:

1) The ``# number'' construct in the element nonterminal of 821

2) The use of domain-literal in the sub-domain nonterminal, as opposed
to the domain nonterminal (e.g. "foo.[128.2.10.102].com") in 822 and
corresponding constructs in 821.

There are also the things which are permitted in either 822 or 821,
but not permitted in the other:

3) The ability in 822 to use quoted-pairs inside of domain-literals

4) The ability in 822 to use quoted-strings for individual words of a
multiple word local-part, as opposed to a single quoted-string as a
local-part.

5) The ability in 821 to use \-quoting inside a local-part

I'm also wondering whether we should slap a "free insertion of
whitespace and comments not allowed inside this nonterminal"
requirement on domain.  Your suggestion for redefining domain happens
to have this effect.
