XForms Document Model ??(including the presentation layer, Business Logic and Data Instances)

I was asked the following question by an interviewer recently. Not very prepared, I did not have the best answer. So I am asking the Orbeon experts here the following question:
what is meant by the XForms Document Model?
How would we answer this question?

thanks

Hi,
I'm running Orbeon on Tomcat 6 and my connection goes through a proxy server. I have a problem when I try to access an internet webservice, where the connection is refused. If I do not go through the proxy server it all works fine.

I'm not sure if this is tomcat or orbeon related, but wondered if anyone had any tips or success stories

Thanks

Ryan

Well, I don't know that interviewer, but I don't know anything called
specifically the "XForms Document Model". I would probably fail that
interview ;-)

This said I can see at least the following uses of the term "model" in
relation to XForms:

* The Model/View/Controller (MVC) architecture generally used by XForms.
* The XForms "data model", which consists in zero or more XML
documents known as instances, as well as associated properties (XML
Schemas, binds, ...).
* Obviously, as in xforms:model and related constructs.
* The HTML or XML Document Object Model (DOM) of XForms and its host
language (i.e. the DOM as present in your web browser or XForms
implementation).

I think here the interviewer must be using "model" as in
"architecture" or "structure" or "organization". With that in mind,
you can elaborate on the above and much more.
