Form Building Invalid XML

With our project, if I use the form to instantiate one of our abstract objects that is in "no namespace", the form builder adds an invalid namespace reference and an xml-fragment element that's invalid. I have to hand fix the XML and validate it before I can send it. Returning to the form tool shows that the form tool can't read the current valid object. What do you need me to send you so you can try it out? The project? The WSDL/XSDs?

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:mgmt="http://www.covergence.com/ws/mgmt">
   <soapenv:Header/>
   <soapenv:Body>
      <mgmt:doAction>
         <action>
            <object xsi:type="ns875:PlayFileType" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><xml-fragment>
   <FileName>?</FileName>
   <To>?</To>
   <!--Optional:-->
   <From>?</From>
   <!--Optional:-->
   <Transport>any</Transport>
   <!--Optional:-->
   <requestId>?</requestId>
   <!--Optional:-->
   <actionIdentifier>?</actionIdentifier>
</xml-fragment><FileName>test</FileName><To>test</To></object>
         </action>
      </mgmt:doAction>
   </soapenv:Body>
</soapenv:Envelope>

As you can see, there is a:

xsi:type="ns875:PlayFileType"

and ns875 is not defined anywhere in the document.

I tried soapUI Pro 4.0 and it's even worse...the form tool shows no choices at all for the abstract objects so something has gone downhill there as well.
