This is starting to look suspiciously like what I have been wanting
for a very long time (typically done with an acyclic directed graph)
- be able to create a heirarchy of query filters, possibly overlayed
with the tree-tag.

Am I correct here? 

BTW, how do you perform the equivalent of the tree tag in Page
