A user relying upon specific class names can easily -introduce- accessibility errors. (And of course anything that requires the user to be able to code CSS is a bad solution.) >- user who want's to read the text first can skip the image and it's >caption and then come back to it later How? >- if user gathers images to a list he can also gather their captions How? What user agents do this? Marja, I don't understand how you think the stated benefits actually occur from the type of markup you used. Yes, those are the right -ideas-, but saying that encoding the page thusly in (X)HTML produces those benefits is incorrect, since I don't believe that any of them actually -work- as you'd like them to work. You could say the same thing about encoding it in XML as well, and it probably makes more sense to do so since the way you want to use classes is not the way classes work, either in practice or in theory. They are the wrong mechanism for doing what you want to do here. ((X)HTML lacks such a mechanism, which is the root of the problem.) --Kynn -- Kynn Bartlett <kynn@idyllmtn.com> http://www.kynn.com/
