	/// <remarks>
	/// Because the Rich Text Format is so versatile, the RTF data format that provides the Formatted Text <see cref="ObjectModel" /> is implemented
	/// first as a subclass on top of the <see cref="RichTextMarkupObjectModel" />. This way we can provide generic RTF parsing functionality in a base
	/// class, and Formatted Text-specific functionality in the subclass.
