Specification of SOAP wsdl for UsernameToken

I'm writing a client to connect to a SOAP webservice using a WSDL first approach. For implementation I am using Apache CXF version 3.1.4

When testing I get the following exception:

12:35:15.492 [main] WARN o.a.c.w.p.a.w.Wsdl11AttachmentPolicyProvider - Failed to build the policy 'UsernameToken':sp:UsernameToken must have an inner wsp:Policy element Exception in thread "main" javax.xml.ws.soap.SOAPFaultException: sp:UsernameToken must have an inner wsp:Policy element at org.apache.cxf.jaxws.JaxWsClientProxy.invoke(JaxWsClientProxy.java:160) at com.sun.proxy.$Proxy36.getPing(Unknown Source) ... Caused by: java.lang.IllegalArgumentException: sp:UsernameToken must have an inner wsp:Policy element at org.apache.wss4j.policy.builders.UsernameTokenBuilder.build(UsernameTokenBuilder.java:52) at org.apache.wss4j.policy.builders.UsernameTokenBuilder.build(UsernameTokenBuilder.java:34) at org.apache.neethi.AssertionBuilderFactoryImpl.invokeBuilder(AssertionBuilderFactoryImpl.java:138)

The relevant part of the WSDL file looks like this:

<wsp:Policy wsu:Id="UsernameToken"> <wsp:ExactlyOne> <wsp:All> <sp:SupportingTokens> <wsp:Policy> <sp:UsernameToken sp:IncludeToken="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy/IncludeToken/AlwaysToRecipient"/> </wsp:Policy> </sp:SupportingTokens> </wsp:All> </wsp:ExactlyOne> </wsp:Policy>

The error message indicates that CXF expects a policy tag under UsernameToken. And indeed, while researching I came across a comment from CXF bug tracker:

Yes... Per spec, the <sp:UsernameToken> element MUST contain an internal wsp:Policy element. It should look like: <sp:UsernameToken sp:IncludeToken="http://docs.oasis-open.org/ws-sx/ws-securitypolicy/200702/IncludeToken/AlwaysToRecipient"> <wsp:Policy> <sp:WssUsernameToken11 /> </wsp:Policy> </sp:UsernameToken>

But, the specification says:

/sp:UsernameToken/wsp:Policy This optional element identifies additional requirements for use of the sp:UsernameToken assertion.

Note: Optional.

So which one is it? It seems that CXf requires a policy while the specification says it is optional. Is there another specification I need to look at?

Seems the question was fairly unnoticed here on SO, but in google leads someone here, I might as well post the solution.

I posted the same question on the Apache CXF user mailing list and got a reply:

It's a bug in WSS4J which I've just fixed: https://issues.apache.org/jira/browse/WSS-564

WS-SecurityPolicy 1.2 + 1.3 require a policy Element, but 1.1 doesn't. Until the next WSS4J release, your best bet is just to have an empty policy Element.
