I like the idea to be able to query XDM nodes, where the queries are
date & time aware, at granularity of the node.
I thought, perhaps can't we accomplish this something like following:
We can have a namespace, which represents the xs:dateTime for a node.
Say, for an element node ("x"), the lexical syntax (carrying creation
& modification time of the node) could be something like following;
<x time:created="2009-10-10T09:00:00" time:modified="2010-10-10T11:00:00">
<!- some children of "x" -->
</x>
We can then query element nodes, in a given date-time range. For
example, as following:
//x[(_at_)time:created gt xs:dateTime('2000-01-01T00:00:00')]
This looks like, to be possible with the existing XDM definition.
