	GetAnnotations<TType>()	Gets a list of annotations of the provided type that are attached to the current element.
	GetAnnotations<TType>(ModelIdentifier)	Gets a list of annotations that are attached to the specified element and whose type matches the provided Type.
	GetComposingChildren	Returns a list of child-composing elements.
	GetHashCode	Serves as a hash function for a particular type. (Overrides Object.GetHashCode().)
