I would hope so.

I'm not clear on what you mean by a "higher level forms application". It 
sounds like you are talking about server-side tags. I don't see how keeping 
business logic out of the client implies server-side tags.

If, OTOH, you are talking about the fact that XForms use XML rather than 
supporting serialized Java objects or ODBC result sets, then I agree that 
this is a restriction but don't agree that it is onerous. Even in a 
client-server architecture, the client needs some mechanism for 
communicating with the database. That communications mechanism can be 
through a web service delivering XML as easily as anything else. And if you 
don't want to define a DTD for your particular data, it can be completely 
generic, like so:

     <resultset>
         <row>
             <col name="CUST_NAME">Acme Explosives</col>
             <col name="ACCT_BALANCE">-12850.25</col>
         </row>
     </resultset>

Since I haven't done anything but request a slightly broader focus for 
XForms, I can't claim to have succeeded at anything in this context.

But those who have designed the XForms spec so far seem to have, unless I 
am just missing your point. Why do you think you cannot use XForms directly 
in a heavy duty order processing application?
