Summary: CAD Services specification needs to clarify 'exact' for    
   nurbs_representation functions.

   nurbs_representation indicates that if the NURBS is exact, then tolerance 
   is returned as negative value.  Is that exact geometrically or exact 
   geometrically AND parametrically?
Resolution: see above
Revised Text: The text on page 2-59 (and similar) was revised as: If the representation is exact - tolerance will be returned as a negative value (geometrically exact = -1  and parametrically exact = -2).
Actions taken:
August 6, 2001: received isue
July 5, 2002: closed issue
Discussion: 
Agreed. To clarify the representation, the document was changed to require that the negative tolerance value indicate: geometrically exact = -1 or parametrically exact = -2.
