It is possible, and it's fairly automatic.

When you call key('k', 'banana'), the system searches for all nodes that:

1. match the match pattern of key 'k'
2. have the 'use' value = 'banana'
3. are in the same document as the context node

So if the context node is in document('abc.xml'), that's the one that is
searched.
