	 * format with the passed buffer. The internal format does not comply
	 * to any standard rich text format and only works between GtkTextBuffer
	 * instances. It is capable of serializing all of a text buffer's tags
	 * and embedded pixbufs.
	 * This function is just a wrapper around
	 * gtk_text_buffer_register_serialize_format(). The mime type used
	 * for registering is "application/x-gtk-text-buffer-rich-text", or
	 * "application/x-gtk-text-buffer-rich-text;format=tagset_name" if a
	 * tagset_name was passed.
	 * The tagset_name can be used to restrict the transfer of rich text
	 * to buffers with compatible sets of tags, in order to avoid unknown
	 * tags from being pasted. It is probably the common case to pass an
	 * identifier != NULL here, since the NULL tagset requires the
	 * receiving buffer to deal with with pasting of arbitrary tags.
	 * Since 2.10
	 * Params:
	 * tagsetName = an optional tagset name, on NULL. [allow-none]
	 * Returns: the GdkAtom that corresponds to the newly registered format's mime-type. [transfer none]
