Whenever an HTML document is re-rendered as an image, such as by being printed on paper or converted to an image document, a person reading the imaged text will have access to the URL only if the URL is visibly included in the content, such as by being made the text content of the <a> element. LIkewise, if somebody reads the HTML document out loud to somebody else or records it orally for others to hear and does not take steps to discover and read out loud the URL, the listening person will not know what the URL is if it is made invisible and thus will be unable to use the URL.
