class Plane from TDataXtd inherits Attribute from TDF

    	
	---Purpose: The basis to define a plane attribute.

	--          gp_Pln of the Plane attribute

    	-- Returns the GUID for plane attributes.

    Set (myclass ; label : Label from TDF)    
    	---Purpose:  Finds or creates the plane attribute defined by
    	-- the label label.
    	-- Warning
    	-- If you are creating the attribute with this syntax, a
    	-- planar face should already be associated with label.

    Set (myclass ; label : Label from TDF; P : Pln from gp)
    	---Purpose: Finds,  or creates,  a Plane  attribute  and sets <P>  as
    	--          generated the associated NamedShape.
