Assuming that $allInput were bound to an arbitrary set of elements 
scattered across a set of documents, would there be any advantage to

$allInput/root()/key('linebyfolio',$folio)

?

The idea being that the documents in question could be consolidated 
before the call to the key function, minimizing the number of calls?

Or is that likely to be taken care of for us, or unlikely to matter much?

Cheers,
Wendell
