Well, I think it would be great if the WCAG group did more maintenance work on WCAG 1, but they have to look at their own resources and set their priorities as they see fit. And since I am not in a position to offer them any resources, I just expect to live with the decisions they have made. In some sense a goal of the EuroAccessibility Consortium was to clarify amongst ourselves these maintenance questions, and then offer the results to the WCAG group as something where most of the work had been done for them and they could simply say "yea" or "nay" to each point. But unfortunately that has also proven difficult through resource constraints. cheers Chaals On Fri, 7 Jan 2005 10:39:53 -0500, Bailey, Bruce <Bruce.Bailey@ed.gov> wrote: > Maybe this should be escalated to GL, I will leave that judgment call to > you Chaals!
