Francois, exhibit has a rule that if you nest a "sublens" _inside_ the
content tags, exhibit automatically iterates through all the multiple
values of a property and concatenates. Hopefully this example makes sense:
<div ex:content=".parent">
<a ex:href-subcontent="#{{.display}}" ex:content=".label"></a>
</div>
Note that in the anchor, I refer directly to .display and .label,
because inside the enclosing div, the "current item" iterates through
the values of the property specified in that div, ie the .parent
