Yes, I've thought about ex:selection. The idea here is to let
ex:itemTypes support the 80% of the cases, and then let ex:selection
catch the rest. You can also mix them, e.g.,
<div ex:role="collection" ex:itemTypes="Publication"
ex:selection="later(.date, offsetDate(now, -1, 'year'))"></div>
will give you publications in the last year (we don't have the later and
offsetDate functions and the now variable yet). And then you can make
more complex selections, e.g.,
<div ex:role="collection" ex:itemTypes="Publication"
ex:selection="and(.spotlight, later(.date, offsetDate(now, -1,
'year')))"></div>
where .spotlight is a boolean property you use to spotlight your
publications.
