Yes, that was one of the clarifications that went into hReview 0.3.

The hListing proposal "forked" from an earlier version of hReview and that's
why it allows that.

The hListing proposal needs to be updated with the same rule(s) as hReview.

We should actually go the other direction, update hListing with the help of
the Edgeio folks.

It is important that microformats iterate and evolve properly, without being
burdened by inertia of early implementations.  We had a similar discussion a
while ago about xFolk.

This assumes that class name order is relevant which is false.

The class attribute is a space separated *set* of class names.


<span class="item fn">Parking space</span>  ==

<span class="fn item">Parking space</span>
