is this SoapUI specific?

Hallo everyone,

I successfully validate this "weird" XML in SoapUI. It looks like this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

   <soapenv:Header/>

   <soapenv:Body>

      <messagecont:dosomething 
                  xmlns:messagecont="http:www.ratna.de/mcb" 
                  xmlns:one="http:www.ratna.de/one" 
                  xmlns:two="http:www.ratna.de/two" 
                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

         <Request>

            <ContractMetaDatas>

               <two:ContractID>ABC</two:ContractID>

               <two:Status>done</two:Status>

               <two:DoneTime>2010-03-06T16:35:51.0Z</two:DoneTime>

               ...

         </Request>

      </messagecont:dosomething>

   </soapenv:Body>

</soapenv:Envelope>

The validation of the file was successfull. I dont understand why the elements "Request" and "ContractMetaDatas" dont need namespace like other child elements? Moreover, I can not recognize any default namespace in the above xml. Is there any in this case? Thank you for your comments.

Regards,

Ratna
