Sorting on complex expressions in Exhibit

[Arithmeticus]

Greetings. In Exhibit, in an viewpanel of collection A related to items from collection B (not shown), I want to invoke a list of properties/objects in B related to each object in A, but in a customized order. So 

<span ex:content=".itemA-attribute!itemB-keywords"> pulls up a list objects from B related to the property in that instance of A, but in B-object-label sequence (alphabetically). How would I sort that list by some other property of B, say by year, descending? That is, I'm looking for something like:

<span ex:content=".itemA-attribute!itemB-keywords" ex:sort=".itemB-year" ex:direction="descending"> 

Is this possible?

I can't think of any way to support this behavior right now. Lenses
don't have a lot of tunability in how they render. If you want to
write some javascript, you could possible write your own code to sort
the spans *after* the item has been rendered (there is an event
triggered when an item is shown; you could bind to that event and
manipulate the dom fragment). you could use the ex:...-content trick
to create an attribute containing your desired sort tag in each span,
but you'd have to do the sort yourself.
