Adding Header to response

Hi All,

For one of my scenarios SOAP - SOAP the incoming file format is like this .

<soapenv:Envelope >

<soapenv:Header>
      <v2:XHeader> 

<v2:Name>?</v2:Name>

         <v2:Id>?</v2:Id>

      </v2:XHeader>
   </soapenv:Header>
<soapenv:Body>
      Body Fields
   </soapenv:Body>
</soapenv:Envelope>

I have done a XSLT mapping to remove the header and then pass it to ECC and then get a response back. The scenario works fine till here. But the problem is the Header field is sending some value under Name based on the different systems. How can I send that information back in response or how can I hold that information in PI and send it back. Because based on the name the same interface will be trigerred by different legacy systems.

So basically Name can be ABC for one system and XYZ for the other. Can someone please tell me how to go about this.
