Re: My Action Item: Multiple interface guideline

By the way, I think this is good and should be incorporated in the next
draft.

  The general idea behind using the server to enhance accessibility is that

  this is a an application of Guidelines 1 and 2, but at a page level rather
  than an element level.
  
  We discussed several techniques for accomplishing this at the F2F, which are
  summarized in my last mail.  My action item dealt with a proposed guideline
  that came out of that discussion.  
  
  On further reflection, I think this is actually a checkpoint, and not a
  guideline.  It could fit in GL 4 of GL 5.
  
  Here's the scenario:
  
  A site author could allow a user to pick from a variety of representations
  of the same data:  a flash version of the content, a version rendered by
  DHTML scripts, or a linear HTML 4.0 AAA Compliant version.  If, however, the
  user picks the flash version, s/he must be able to get back to the other
  versions whether or not s/he can access the flash version.  The control for
  switching between versions must be accessible, even if the version the user
  has selected is not.  
  
  And here's the checkpoint:
  
  x.x When multiple interfaces are provided for the same content, the
  mechanism for switching between interfaces must be accessible and easy to
  find.
  NOTE: The switching mechanism must be accessible even if the currently
  selected interface is not.  This ensures that a user who has selected it by
  accident will be able to recover.
