Remarks

A global ambiguity occurs when the same span of text in a document can be interpreted in two or more different ways based on the grammar rules for the language and the context in which text occurs. Code handling global ambiguities can determine which sub-trees should be used in the final tree by setting PreferredSubTreeRoot.

Note: The only valid values are null or the instances returned by SubTreeRoot1 or SubTreeRoot2.
