Hopefully, the browser will be doing real-time in-line validation,  
instead of waiting for the form to be submitted. In such a case, there  
is less need for a centralized error list (although it might also be  
handy to have one as a menu or something in the UA UI, for people who  
pay less attention to the messages they get while typing).

I just read an excellent ALA article about this, from Sept. 1, which  
should be required reading for anyone involved in these issues:
