Question on Use Case: Choosing atom:content's type when Archiving Mailing Lists

[Andreas Sewe <ans208@xxxxxxxxxxxxx>]

I have a question regarding a specific Atom use case: What is 
the preferred way to set up an Atom feed listing the contents of 
a mailing list's archive, given that composite media types (in 
particular "message/rfc822") are disallowed for atom:content's 
type attribute? This prevents me from doing something like the 
following, serving the archived mails "as-is" via HTTP:

<atom:content type="message/rfc822" 
src="http://www.example.org/lists/list/archive/12345"/>

But then again there might be something more fundamentally wrong 
with serving mails as "message/rfc822" via HTTP than I currently 
realize -- and I should better serve the mails as "text/plain" 
or convert them to HTML first (which is the way the atom-syntax 
archive works).

Nevertheless, any advice on this issue would be greatly appreciated.

Regards,

Andreas Sewe
