Access: [6.5.1.1]: <frameset> missing <noframes> section
(Priority 2)

Cause:

Each <frameset> must include a valid <noframes> section which has at least one word of text or accessible html code and all links required to navigate the site. Do not use the <noframes> section to inform users that they must upgrade to a browser that supports frames.

Testfile:
