I think the current example works well with @class.

I can see either <class name=''/> or <class id=''/> working.  It makes no
difference to me...  Also, IMO, I don't see any need for forcing an @id on
every element unless it's necessary for some type of linkage.

One other comment on the example XML file.  Right now we have a couple of
objects layed out like so:

<field
 name="start_date_day"
 virtual="false"
 type="object"
 class="date">

Here, @type should be 'string' since that's how dates will be encoded.
