This wouldn't really be a Template sort of thing to do,=20
it is a framework sort of thing.=20
Form validation depends upon the objects you are putting into=20
and taking out of the form, which implies a commitment to a=20
particular persistence layer.

<plug>
Melati, which uses WebMacro, has two mechanisms=20
for validation: client -side javascript and server-side=20
validation (as defined by the Data Structure Definition).

You, the programmer, get this for free when you buy into the=20
POEM middleware layer.

The client side javascript may be of interest, as it is=20
independant of POEM/Melati
