any suggestions?  what ideas in particular need to be expanded?

we changed both of them to ANDs.

we have included the following definition of "screen reader" in the
appendix, and will link to it from throughout the guidelines:
Screen reader
A software program that reads the contents of the screen aloud to a user. 
    Used primarily by individuals who are blind, screen readers can only read 
    text that is printed, not painted, to the screen.

>#3, Current >>>>>>>>>>>>>

yes, this is exactly what it means.

we have moved 2 to 3, and added the phrase "Guidelines A.1 - A.12 address
these issues." after the list of 3.

thanks for your comments!
