Starting in 3.4, the objects may have multiple citations.

Internally, this class maintains a list of Citation handles,

as a citation_list attribute of the CitationBase object.

This class is analogous to the notebase class.

Both these have no attributes of their own; in this respect, they differ

from classes like MediaRef, which does have attributes (in that case,

privacy, sources, notes and attributes).

class. I.e. SourceRef = CitationBase + Citation
