SOAP Body-Root Tag with our NameSpace-IS 6.5

Is there anyway to trick soap utilities(pub.soap.utils:addBodyEntry) on WM6.5 to allow adding an xml with root node which doesn’t has a namespace associated to it in to the soapBody(see highlighted tag below).
When I try to add an xml like below

<ns1:Details xmlns:ns1=">
John Doe

in to the SOAP Body using pub.soap.utils:addBodyEntry; its throwing the Error: Invalid Body Entry. SOAP Body Entries must have a namespace name.

Any help is appreciated.
