	/// DOM operations only raise exceptions in "exceptional" circumstances, i.e.,
	/// when an operation is impossible to perform (either for logical reasons,
	/// because data is lost, or because the implementation has become unstable).
	/// In general, DOM methods return specific error values in ordinary processing
	/// situations, such as out-of-bound errors when using NodeList.
	/// 
	/// Implementations should raise other exceptions under other circumstances.
	/// For example, implementations should raise an implementation-dependent exception
	/// if a null argument is passed when null was not expected.
