Hi Kumar,
WS-A is a standard and as such there should be online XSDs that define the schema. (https://www.w3.org/2006/03/addressing/ws-addr.xsd)
Based on the XSD, you can create your document type definitions.
When calling the SOAP service, populate this doc types and send them with the call.
The reference that M@he$h mentioned will help you with that.
