Sounds good, but may have problems in practice.

We're working on a series of large, complex (existing) application forms 
which need to be available in HTML and the results fed into a workflow 

There are three key players here: the workflow system developers, the 
business process owners, and the form-design people. Each group has 
different, legitimate, interests in creating something that is 
straightforward for their own systems and their own 'customers' within 
and without the business. We have found that attempting to create a 
common schema that can self-create a form to be an elegant theory but 
not realistic.

We have found that Xforms' decoupling of the user-interface from the 
data schema to be an extremely useful thing. We are writing the form/UI 
in XML (actually, a format which outputs to XML) to a UI-aligned schema 
and mapping the result to the workflow data schema. The output of that 
is Xforms, and the Xform is the source, in turn, of the HTML which the 
user sees.

I don't know if this is the 'right' way to approach the task, but it 
seems to be working for us. I'd be happy to hear about other approaches...
