Hmm.. I'm not really sure we need anything more than simple HTML semantics
(given by the spec) and a small microformat/microdata.

I'll use <q> or <blockquote> in the example.

<span class="vcard"><a href="http://example.com/justin" class="url
fn">Justin</span> said:</span>
<q cite="http://example.com/justin/msg/12345">I agree.</q>


<blockquote cite="http://example.com/justin/msg/12345">
<p>I agree.</p>
<p class="vcard">— <a class="url fn" href="http://example.com/justin

If you prefer microdata:
(just the Person bit)

<p itemscope itemtype="http://data-vocabulary.org/Person">
     <a itemprop="url" href="http://example.com/justin">
          <span itemprop="name">Justin</span>

If you still think you need a more formal vocabulary, please read:
