[Versa] Question about query

[Michael Olson]

The following is a legal expression in Versa:

   <http://foo.com>

It can be used as a filter expression in a filter or traversal and it  
returns a boolean value if the resource matches, etc.

My question, is what if this is the top level expression and executed  
on an empty model.  What are the results of the expression?

Is it a boolean?

Is it null because the resource does not exist?

Is it just the resource's URI regardless of whether or not it exists?

I think it should be the empty set.

Mike
