Input elements are highlighted and automatically scroll into view.  So I'm not sure I could use something like JSF validation.

You can do whatever you want.  It's your choice.  But there's absolutely 
nothing to putting all the message lines in the top.  In fact, there is 
a special tag that supports all the messages rather than individual 
messages; that tag could be placed at the top of the form.

I won't debate the pros and cons of your UI style.  I'm sure you've 
heard arguments on both sides.  I will say that without too much work 
you ought to be able to get the messages to appear wherever you want 
them to appear.
