5.1.5 Frame equivalents
Checkpoints in this section: 4.12 and 4.11. 

Some user agents cannot render graphically defined frames or the user may
turn off the rendering of frames through configuration for improved access
to document content.  In this case the user agent should render the
contents of NOFRAMES for the document. 

Lynx is an example of a user agent that cannot render frames:

*** insert lynx example from 3.3.6 ***

pwWebSpeak version 2.5 (Release 14) is a speech based user agent and
indicates the presence of frames and renders the no frames content.   The
frames information rendered visually and auditorially through generated
speech though does not render the title or the name information associated
with the frame elements.  The rendering of title or name is important to
provide the user with access to descriptive labels for the frames defined
by the document author.

The following image shows a possible view of a graphical user agent if the
user could turn off the rendering of frames.

The image shows both the links to the original frames and access to the no
frames content.  Links at the top of the page allow the user to be oriented
to the availability of the no frames information and also links to the
frame elements.  The links allow the user to directly move to either
location of information in the document.  Access to the original frame
elements is important since many times the only information in no frames
content is a statement to the user to use a frames compatible user agent.
By making links to the frame elements available, the user still has the
option of exploring the individual frame elements.  The title attribute
should be used as the first source for a descriptive label for the frame
element.  An alternative source for descriptive label is the name attribute.
