Notes:
Note that a Collection can have more than one Documents with the same
External Id. These Documents will all have the same External Id but
they will have different Document Ids. This function will make the proper arrangments so as a call to
tip_NextDocument (or tip_NextDocument) will return the Document that
was created after the one returned by this function.
This function is equivelant to CDM_GetByExternalId (C++ API).

tip_Close, tip_GetDocument, tip_NextDocument
