deferred class ADriver from XmlMDF inherits TShared from MMgt
---Purpose: Attribute Storage/Retrieval Driver.
uses
AsciiString from TCollection,
ExtendedString from TCollection,
Attribute from TDF,
MessageDriver from CDM,
RRelocationTable from XmlObjMgt,
SRelocationTable from XmlObjMgt,
Persistent from XmlObjMgt,
Element from XmlObjMgt
is
Initialize (theMessageDriver : MessageDriver from CDM;
theNamespace : CString from Standard;

VersionNumber(me) returns Integer from Standard
is virtual;
---Purpose: Returns the version number from which the driver
-- is available.
NewEmpty (me)
returns mutable Attribute from TDF
is deferred;
---Purpose: Creates a new attribute from TDF.
SourceType (me) returns Type from Standard;
---Purpose: Returns the type of source object,
-- inheriting from Attribute from TDF.
TypeName (me)
returns AsciiString from TCollection
