Let me see if I can reword this:
The traversal filter attribute in a graph parser query limits the documents
which get traversed. I'd like to limit each document using a value from the
parent document. For example
only traverse child documents which have a start time 10 minutes greater
than the parent documents start time. Is it possible to write a traversal
filter in that way?
