About web-service security along with Session management soap header

Dear All,

I have confusion related to WS security along with session management.

We have implemented web-service security using WS security tokens as below token:

eg:

<soapenv:Header>

<wsse:Security xmlns:wsse="http://schemas.xmlsoap.org/ws/2002/07/secext">

<wsse:UsernameToken xmlns:wsu="http://schemas.xmlsoap.org/ws/2002/07/utility">

<wsse:Username></wsse:Username>

<wsse:Password Type="wsse:PasswordText"></wsse:Password>

<wsse:SessionType>None</wsse:SessionType>

</wsse:UsernameToken>

</wsse:Security>

</soapenv:Header>

I am curious to relate it to 'Siebel Authentication and Session Management Soap Headers'.

eg:

<soap:Header>

     <UsernameToken xmlns="http://siebel.com/webservices"></UsernameToken>

     <PasswordText xmlns="http://siebel.com/webservices
