I found the answer to #1, mentioned in another response, and I just
found out how to have dynamically generated labels. Simply:
<div t:type="loop" t:source="propertyTypes"
value="propertyType" encoder="encoder">
<t:checkbox t:id="ptype" t:value="propertyType"
t:label="prop:propertyType.name"/>
<label t:type="label" t:for="ptype"></label>
</div>
Notice the t:id in the checkbox and the t:for in the label. They are
"hardcoded", which I thought would throw exceptions. But no, T5 knows
they're being looped and just handles it. Awesome!
