deferred class Pattern from TDataXtd inherits Attribute from TDF

	---Purpose: a general pattern model

uses 
     Array1OfTrsf from TDataXtd,
     LabelList    from TDF,
     GUID         from Standard

is

    GetID (myclass)   
    ---C++: return const &  
    returns GUID from Standard;    
   
    ID(me)
    	returns GUID from Standard
	is redefined static;
	---Purpose: Returns the ID of the attribute.
	--          
	---C++: return const &

    PatternID(me)
    	returns GUID from Standard
	is deferred;
	---Purpose: Returns the ID of the attribute.
	--          
	---C++: return const &

    NbTrsfs(me)
    returns Integer from Standard
    is deferred;
        ---Purpose: Give the number of transformation

    ComputeTrsfs(me; Trsfs : in out Array1OfTrsf from TDataXtd)
    is deferred;
        ---Purpose: Give the transformations
