HI Shailesh
I agree with you, in case of work flow. Yes but only needed for business
as you said in workflow. 
But for other validations for checking domain constraints with respect to
XSD should be better
done in the client.

Server side validation and workflow can not be eliminated. However, with a
client side validation, round trips to the server could be minimized,
eventually improving performance at server side and increasing the response
time at client side. But, this is a more of a concern for internet
applications. For corporate/intranet applications, if the same XForms client
is deployed, one can trust its validations for more efficient processing.

try http://chiba.sourceforge.net. Though not yet complete it's used in 
different commercial project with success. Chiba transcodes your XForms 
into html and gives you some xml to work with.

btw, there another strong argument for a server-side component: 
server-side validation. - what about all that wonderful xforms 
validation stuff after your form is sumbitted via the internet? will you 
really work with only client-side validated input? - just a thougth, but 
IMO a serious problem for the pure client-side approach.
