deferred class ADriver from BinMDF inherits TShared from MMgt
---Purpose: Attribute Storage/Retrieval Driver.
uses
ExtendedString from TCollection,
MessageDriver from CDM,
AsciiString from TCollection,
Attribute from TDF,
RRelocationTable from BinObjMgt,

is
Initialize (theMsgDriver: MessageDriver from CDM;

NewEmpty (me)
returns mutable Attribute from TDF
is deferred;
---Purpose: Creates a new attribute from TDF.
SourceType (me) returns Type from Standard;
---C++: return const &
---C++: inline
---Purpose: Returns the type of source object,
-- inheriting from Attribute from TDF.
TypeName (me)
