Re: Tentative meeting on the DOM with AT vendors for the User Agent Guidelines

Mark,

I am not sure what you mean by presentation *style*. Are you suggesting
syle in the way that we present the issue to ATs?

I didn't think you were suggesting we create another standard. What I
thought you were doing was suggesting that a user agent could create
whatever interface they wanted for accessibility and not comply to the DOM
standard when it pertains to the document.

hi Rich

I'm not suggesting we don't use DOM, and I'm not suggesting
we create yet other standard.  I'm suggesting that presentation
*style* can make a huge difference in whether or not someone
"buys-in" to an idea.

regards
