I thought the were going to be equal because they are part of the same 
context.  Is there a way to compare the pair-wise unequal $unique-rooms to 
say an a sibling node with similar data?  Is context part of the select 
statement?  If I select //topics/topic/location am I in the location 
context, if so can I compare "." to //topics/place/room data?  If not, 
please explain or send some keywords about my learning deficits so I may 
be engoogled.
