I can think of lots of reasons that validation is really important, but 
the two main ones are:

1, It means that groups like thoughs working on the DHTML road map that 
Becky mentioned will make a formal , published , DTD  (DTD - A short 
file that defines their terms).

If we did not have that then groups could band together with a chosen 
assistive technology, using a closed unpublished grammar, to make 
"accessible content" that works with that one assistive technology (say 
the market leader). If you do not happen to like that assistive 
technology, or it does not happen to address your access needs - well 
that is just market forces...

2, Assistive technology need to parse content to manipulate it for the 
user. The better they can do that  the better will be the user 
experience. Now some authors/tool make very innovative but bad mistakes 
that mess up the whole concept of adaptive content.

Validate and we stay OK

I think this is a really important one folks.

All the best
