One more question - what's supposed to be the difference between H67, F38 and F39?  The latter two appear to be identical - and H67 appears to be a subset of F38/F39 that only applies to IMG elements (whereas F38/F39 apply to IMG and APPLET elements).

Any reason not to simply define H67 as applying to both IMG and APPLET elements and just drop F38 and F39?  Or better, simply leave APPLET elements out of it - they're very rare these days and I don't believe I've ever seen a purely decorate JAVA applet anyway.

The ERT WG home page is http://www.w3.org/WAI/ER/ . You can find
additional information  there, including contact information.

However, manual verification of, say, pages that contain "audio-only presentations" is more realistic - this assumes that there is an automated method of recording pages that use such presentations.  It would be nice if there was standard XHTML markup to identify presentations as audio-only / video-only / etc.
