persistent implemention of storage.
The application must redefine one the two Make()
methods. The first one, if the application wants to
put only one document in the storage file.
The second method should be redefined to put
additional document that could be used by the
retrieval instead of the principal document, depending
on the schema used during the retrieval. For example,
a second document could be a standard
CDMShape_Document. This means that a client
application will already be able to extract a CDMShape_Document
of the file, if the Shape Schema remains unchanged.
