  I would assume the brunt of Manuel's class is its server-side
checking. The javascript is, as he said, an *addition*, an addition
which, when javascript happens to be available, obviates the need for a
round trip to the server just to say some field data was unacceptable.
Sounds good to me.

  Fair enough, bears repeating.
