class TFace1 from PBRep inherits TFace1 from PTopoDS

	---Purpose: The TFace1 from PBRep  is  based  on the TFace1  from
	--          TopoDS. The TFace1 contains :
	--          
	--          * A surface, a tolerance, a location
	--          
	--          * A NaturalRestriction flag,   when this  flag  is
	--          True the  boundary of the  face is known to be the
	--          parametric space (Umin, UMax, VMin, VMax).
