Hi Klotz,

Klotz said:
  Why use //description, etc rather than /demo/description?

Actually, since XForms sets the XPath context node to be the document
element, you can jus tsay
       <xforms:bind id="version" nodeset="version" constraint=". = '1.0'"/>
       <xforms:bind id="name" nodeset="author/name"/>
       <xforms:bind id="email" nodeset="author/email"/>
       <xforms:bind id="description" nodeset="description"/>

  <!-- snip -->

Didier replies:
Yes you are right about /demo/description.

Klotz said:
Actually it would be
    <xforms:input
ref="version"><xforms:label>Version</xforms:label></xforms:input>

Didier replies:
Only if you want to use xforms widgets. If you implement the XForms engine
with XSLT which is, by the way, a kind of interpreter, and if you want to
use XHTML widgets, then you use 
<xforms:submission id="submit" 
                            xforms:replace="all"
                            xforms:action="http://mydomain.com/MyStorage"
                            xforms:method="PUT"/>
     <xforms:instance src=http://myDomain.com/theChallenge.xml" />
                            .....
                            .....
     <!-- an XHTML widget -->
     <input ref="demo/version" type="text" name="version" size="20"/> 

Klotz said:
Note that the context node being "/data" means that you can just use the ref
to ne the immediate child name of the toplevel element,
so it looks a lot like what XHTML 1 does with <input name="version"/>.  In
fact, if you omit the <instance> from a model entirely,
XForms will notice that and make one up for you populated by elements with
names taken from the form controls bound to the model.
It's a good transition step from XHTML 1 to XHTML 2 or other XForms host
languages.

Didier replies:
I wasn't able to find what the spec says about that. Do you know where that
process is specified?
