SOAP attachments

SOAP MIME attachments are producing XML with cid referenced as an href="cid:*****" attribute as follow :
<DataHandler href="cid:******" />.
In my case, the WS provider application is expecting the cid reference as tag content as follow :
<DataHandler>cid:*****</DataHandler>
This specific tag :

• is referenced in WSDL as a " wsiRef:swaRef" type
• with xmlns:wsiRef="http://ws-i.org/profiles/basic/1.1/xsd&quot;

Is it possible to get the cid reference as tag content instead of href attribute value ?

Thanks
