Text-only pages should not be necessary to ensure accessibility of
Web pages that follow the "Web Content Accessibility Guidelines," except
in very rare cases.
In fact, text-only pages are frequently counterproductive to accessibility
since they tend to be kept less up-to-date than "primary pages," or
in some cases leave out information that is on primary pages.
Many sites that have made a commitment to accessibility in the past
have used text-only pages as a solution; however, by following these
guidelines it should be unnecessary in almost all cases, or even inadvisable,
to set up and maintain a separate set of text-only pages.
