Precondition p1: There is a means for a user to select that alternative

Test 0001 Assertion: The user can choose to render any type of
alternative content that is available for any element

IF content_element contains alternative_content THEN
	indicate alternative_content is available
ENDIF

IF content_element contains anchor to alternative_content THEN
	indicate alternative_content is available
ENDIF

IF alternative_content chosen (Predicated on p1) THEN
	IF anchor THEN
		BEGIN
			resolve anchor; retrieve content
			generate alternative_content from retrieved
		EXCEPTION
