I wonder who you're talking about ?
I have a few remarks on the *draft*, so I'm saying them. Once it'll be a
recommendation, it'll be too late.

In my example, everything was inline and made simple to be concise.
Let's go for a real-life, pratical example. I hope you'll like it.

Let's say I'm running an e-commerce site.
I have a XML catalog at http://mysite.com/catalog.xml.
Since my customers can save their basket between sessions, the current
basket of a customer is available at http://mysite.com/basket.xml
(identification being made with the help of cookies or whatever).
Of course, my form needs some working variables.
I might end up with something like that:

<html>
 <head>
  <xform:model id="catalog">
   <xform:instance xlink:href="http://mysite.com/catalog.xml"/>
...
  <xform:model id="basket">
   <xform:instance xlink:href="http://mysite.com/basket.xml"/>
...
  <xform:model id="working_variables">
   <xform:instance>
    ...
   </xform:instance>
...
</html>

So, this is a practical situation, how do you rewrite it with only one model
? Of course, it isn't allowed to write a server-side script, you must use
pure XForms.
