FYI, there was also a project done by Joern Turner of Chiba a few years ago called schema2xforms.
It's looking for a new maintainer so if you are interested in this area more generally, you might look there.

Personally I've started looking at WADL and XForms, as you can tell from my postings here...

Iņaki,

If your use case meets the following conditions:

* Labels and values are the same
* The enumeration is defined in the XML schema

then you can load the schema in a separate instance and bind your
itemset to the enumeration.

For example, say you have this in your schema:

   <xs:simpleType name="state">
     <xs:restriction base="xs:string">
       <xs:enumeration value="AL"/>
       <xs:enumeration value="AK"/>
       ...

In the model, do:

   <xforms:instance id="schema-instance" src="schema.xsd"/>

and in the view, within a selection control:

   <xforms:itemset 
nodeset="instance('schema-instance')/xs:simpleType[@name = 
'state']//xs:enumeration">
     <xforms:label ref="@value"/>
     <xforms:value ref="@value"/>
   </xforms:itemset>

We do this in our Government Forms example at:
