to/cc/bcc extension

[James Snell]

Wanted to draw attention to this:

  http://tools.ietf.org/html/draft-norris-atompub-audience-00.html

It introduces to/cc/bcc elements to an Atom entry.

  <entry>
    ...
    <to>acct:john....@example.org <acct%3ajohn....@example.org></to>
    <to>acct:b...@example.org <acct%3a...@example.org></to>
    <cc>acct:jane....@example.org <acct%3ajane....@example.org></cc>
    <cc>acct:j...@example.org <acct%3aj...@example.org></cc>
    <bcc>acct:jean.d...@example.org <acct%3ajean.d...@example.org></bcc>
    <bcc>acct:m...@example.org <acct%3a...@example.org></bcc>
    ...
  </entry>

Comments are welcomed and requested.
