Jon, 1. Perhaps some verbiage needs to be added to the Note for checkpoint 2.1 to the effect that this does "not require that all content be available at all times". 2. I suggest that the issue regarding the definition of "Text content" await the forthcoming revision to the definition of "Text content"... The revision may make the current discussion unecessary. - Eric > -----Original Message----- > From: Jon Gunderson [mailto:jongund@uiuc.edu] > Sent: Monday, January 29, 2001 1:01 PM > To: Hansen, Eric > Cc: UA List (E-mail) > Subject: RE: Instruction and Assessment > > > I think language on restricting access to content for some > "higher" purpose > is very dangerous.
