Remarks
An object representing transient annotations is in one of these states: 1) Null, if the element has no transient annotations. 2) An EdmVocabularyAnnotation, if the element has exactly one annotation. 3) A list of EdmVocabularyAnnotation, if the element has more than one annotation. If the speed of annotation lookup for elements with many annotations becomes a concern, another option including a dictionary is possible.
