ATAG20 Glossary Updates

Hi,

As I was putting the new definition proposals into the Glossary I saw a 
number of other issues, some editorial and some more substantive. I have 
therefore made some proposals (including marking the source of 
definitions within WAI).

The proposals are marked up in a new Editor's Draft at:
http://www.w3.org/WAI/AU/2007/WD-ATAG20-20070810/WD-ATAG20-20070810.html

Let's try to deal with some of these during our Monday meeting.

Cheers,
Jan
