The authors chose to limit DAV:scope to one element because when if a query 
can apply to more than one resource, it is possible for the two resources 
to have very different query schema.  In this case it is quite difficult to 
specify the semantics for the query.  Several of the authors (not me) had a 
lot of experience in doing this across SQL databases, and said it was very 
hard to define correctly.  Therefore we chose to handle only the simple 
case for now, and leave the complex part for later.

Is this acceptable to you?
