A DOM user should be able to add an entity reference node to a document
without its entity declaration.
The Open problem is that DOM2 specs don't allow to add entity declarations
to thet DocumentType interface of a Document. So or the DOM implementation
have to do this for the user or the DOM implementation have to document
that when a user add an entity reference node that doesn't have an already
declared entity declaration the resulted DOM tree will not can be a
parsable XML file.
