Given that it is meant primarily as a data exchange protocol, explicit is 
better, so I'm preferring Microdata instead of Microformats here.  Also, it 
seems Google already has a registry of formats, and one is "Person" which may 
be reusable.

Now we have this:

  <span itemscope itemtype="http://data-vocabulary.org/Person" 
itemid="acct:justin at example.org">
    <meta itemprop="context" content="reply"/>
    <a itemprop="url" href="http://example.org/justin/"><span 
  </span> I totally agree.

We are still debating whether it makes sense to add "context" in here, but 
that discussion is not necessary for this mailing list.

Thanks for your help in pointing me in the right direction.
