How can I add some text from Groovy script directly to response in SoapUI
===

 if for example I have to set the value 

    <oa:Status>
    <oa:Code>-1</oa:Code>
    <oa:Description>Unable to process the request within specified time</oa:Description></oa:Status>

To the response in soapUi, for example after some tag...How can I do this?
