RE: Another problem with missing schema types (v1)

I remember making what I think is the fix for this problem in the V2 codebase 
and not being the easy one. If using V2 is not an option, I'll have to go back 
and see what it would take to port the fix over.

Subject: Another problem with missing schema types (v1)


A long time ago I had a problem using xmlbeans on the j2ee 1.4 schemas  
from sun since they had duplicate uniqueness constraint names, as Radu  
very kindly pointed out.  Eventually Sun fixed the schemas and all  
seemed well.

However, I've just come across what may be a related problem that I  
don't think can be blamed on Sun so easily.

The j2ee_web_services_client_1_1.xsd has this group:

   <xsd:group name="service-refGroup">
     <xsd:sequence>
       <xsd:element name="service-ref"
                   type="j2ee:service-refType"
                   minOccurs="0" maxOccurs="unbounded">
        <xsd:key name="service-ref_handler-name-key">
          <xsd:annotation>
            <xsd:documentation>

              Defines the name of the handler. The name must be unique
              within the module.

            </xsd:documentation>
          </xsd:annotation>
          <xsd:selector xpath="j2ee:handler"/>
          <xsd:field xpath="j2ee:handler-name"/>
        </xsd:key>
       </xsd:element>
     </xsd:sequence>
   </xsd:group>


As you can see, this is a key inside a group.  The group eventually  
gets used in 5 places (3 ejbs, web-app, and app-client).  Compiling all  
the schemas with xmlbeans appears to go fine, and I end up with a  
schema type named like this:

schema.system.s36B98A072B910FA7209F8F5FBD7FF0A3.servicerefhandlernamekey 
identityconstraint5

However, when I attempt to validate a web.xml containing a service-ref,  
it looks for

schema.system.s36B98A072B910FA7209F8F5FBD7FF0A3.servicerefhandlernamekey 
identityconstraint4

which is not present, so validation fails.

a:351)

I'm speculating that xmlbeans is in some sense replacing each group  
usage with a copy of its contents, thus effectively generating 5 keys  
with the same name.

So, my questions are,
1. Is this a bug in xmlbeans v1, or is there something wrong with the  
sun schema?

2. Should it work in v2?

Many thanks,
david jencks
