				interface for those accessibility features has been documented by the
				manufacturer of the operating system and is available to the product
				developer.
(c) A well-defined

				a range of contrast levels shall be provided.

				blinking text, objects, or other elements having a flash or blink frequency
				greater than 2 Hz and lower than 55 Hz.
