The abstraction of the validation logic with min/max values and filters is
very welcome indeed.  I was wondering if there was an opportunity to cope
with even more complex validation issues without resort to script code on
the client side.  My beef with the client side script code performing the
validation is simply that in many circumstances what is being validated are
not simple min/max ranges, but algorithms that should be defined and
implemented in the middle-tier.  

I was thinking that it might be an idea to be able to have the middle-tier
define/generate the script and pass this in an XML block to the client-side
where it is unwrapped and hooked into a control.  This clearly would involve
more than just XForms, but wouldn't it be marvelous? A total end to
validation algorithmic duplicaiton without unnecessary round-trips to the

I'm probably missing the point, and am ready for a barrage of insults!  I
love what is being proposed it looks a far cry from the terrible HTML/ASP
nonsense I am currently working with.
