I hate to answer my own post, but what if I did something in a customer
Validator? What if the error returned by my validator was something like
SPAN("blah blah", _class="warning"). Presumably I could search the FORM
using elements() finding my SPANs and then modify the enclosing DIVs to be
class "warning" also. I'd provide different CSS for the yellow background.
Just thinking out loud here.
