If there were any one particular wart in 822 that it would be reasonable 
to "by gentleman's agreement" ignore, it would be this requirement for a
non-null phrase.  Nevertheless, I think what we are talking about doing
(translating an address from one domain to another) falls into the category
of "munging".  The existing RFC standard for header munging suggests the
unmunged address be included as a pseudo-comment in the munged address.
This can simultaniously satisfy the syntactic requirement for "phrase".

So one might want to translate the address:

fee!fie!foe!fum!jack

into:

"fee!fie!foe!fum!jack" <@fee,@fie,@foe:jack@fum>

Seems as reasonable a default as any... My Internet to BitNet relay 
implementation does just this.
