Great article Elliot and nice to see designers embracing microformats.

I can see the argument for using a list but in which case howsabout a definition list? This will maintain a semantic (human readable) association when microformats are unavailable through name-value associations and the definition terms can be hidden/styled appropriately with CSS if required.

For example:
<dl>
<dt>Street address</dt>
<dd class=“street-address”>25 Laughingallthe Way</dd>
…
</dl>

Just a thought…
