Refernce in SOAP request

Hi,

Is there a way to use refernce in SOAP, something like this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:nm="http://com/aaa/bbb/">
<soapenv:Header/>
<soapenv:Body>
<nm:Request1>
<argsList>
<entity name="myRequest">
<number>24919</number>
<hidden>false</hidden>
</entity>
</argsList>
<argsList>
<entity ref="myRequest"/>
</argsList>
</nm:Request1>
</soapenv:Body>
</soapenv:Envelope>
