Chained validators don't have access to previous errors.  The actual
validation produces an exception that contains all the errors.  @validate
then runs those through htmlfill.  I'm not sure if there's a way to get into
@validate; you might want to ask on the Pylons list.

I'm not sure what you mean?  Oh, like redirect to #top?  You could change to
<form action="page#top">; for successful submissions that shouldn't do
anything, but for unsuccessful submissions you'd go to the top.
