Interface	Description
SpanNodeParent	An interface to be implemented by classes that can be parents of SpanNodes.

Class Summary

Class	Description
AlternateSpanList	A node in a SpanNode tree that can have a multiple trees of child nodes, each with its own probability.
Annotation	An Annotation describes some kind of information associated with a SpanNode.
AnnotationReference	A FieldValue which holds a reference to an annotation of a specified type.
AnnotationReferenceDataType	A data type describing a field value having a reference to an annotation of a given type.
