	These are intended to support semantic markup.  There are a number
	of places in the documentation where the exact meaning of an
	indentifier marked \code{} in the running text is ambiguous (could
	be a module or a class, a function or a method, etc.).  These are
	intended to clarify the intent of the identifier for processing
	applications and more intelligent style processing.
