Hi Gregg, <blockquote> > 8. WAI will be creating guidelines for creating > baselines - as well as creating sample Baselines for 2007. </blockquote> I have a question on this. Will WAI also do that for Japanese? What about the other languages than English? The user agents' support would be different among the languages. - Makoto 2006/9/7, Gregg Vanderheiden <gv@trace.wisc.edu>: > > > > We have been working on a better short description of the baseline concept. > Here is a version to comment on. > > > > Easier to understand?
