[Nsi-wg] Query types

[Jerry Sobieski]

Why differentiate between a "detailed" query and a "recursive" query?  
They return the same thing.   If you only want detail to a particular 
level, then put a depth parameter on the Query so that it knows to only 
go so deep recursively.   If you only want detail from a single NSA, 
depth=0 (or 1 depending on how you want to interpret it).   The 
recursion stops when the stack gets so deep.

Are you planning to walk the tree yourself?    The reason we defined the 
recursive query was that the notion of walking the tree via independent 
agent got roundly criticized in Salt Lake City - no one wanted to do 
that.   People were upset that they would have to work to get path 
information.  So we landed on a recursive query where authorization 
would follow the same criteria down the tree and the whole result would 
be returned with one pretty bow on it.
