changing namespace prefixes in soap message with wwsapi - c

Question

I'm using WWSAPI inside a C project to communicate with a web service by sending and receiving SOAP messages.
The error I'm having is that The server is expecting to see a <wsse:Security> tag and the message generated by my program doesn't have one. Instead it has a <o:Security> tag. Is there a way to specify the namespace prefix within WWSAPI for C/C++?
Here is my request:
<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Header>
<a:Action s:mustUnderstand="1">http://ge.evse.com/getAllGeneratedPasswords</a:Action>
<a:MessageID>urn:uuid:1fc3d3dc-a1c1-4fcf-bfca-96e712afba1b</a:MessageID>
<a:To s:mustUnderstand="1">https://services.stg.gewattstation.com/EVSEManufacturingServices/services/EVSEManufacturingServices</a:To>
<o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
<Timestamp xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">

</Timestamp>
<o:UsernameToken>
<o:Username>joe</o:Username>
<o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText"><!--censored sensitive information--></o:Password>
</o:UsernameToken>
</o:Security>
</s:Header>
<s:Body>
<getAllGeneratedPasswords xmlns="http://service.services.manufacturing.evse.inds.ge.com/">
<userType xmlns="">user</userType>
</getAllGeneratedPasswords>
</s:Body>
</s:Envelope>
And here is the Response from the web service:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<soap:Fault>
<faultcode xmlns:ns1="http://docs.oas is-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd ">ns1:InvalidSecurity</faultcode>
<faultstring>An error was discovered processing the <wsse:Security> header</faultstring>
</soap:Fault>
</soap:Body>
</soap:Envelope>
As you can see, it's looking for <wsse:Security> and it isn't seeing it... anyone who knows anything about this?
