OpenSAML user discussion

[Ted Hesselroth <>]

I would like to use StatusMessageType to pass information on errors in 
the PDP, but the needed classes are not implemented in 2.1. Perhaps they 
are meant to be in 2.2. Anyway, I attach some code here, which I am now 
using. I had to add some lines to the StatusMessageType code. Also, 
these lines need to be added to xacml20-context-config.xml.

       <!-- StatusMessageType -->
       <ObjectProvider qualifiedName="xacml-context:StatusMessage">
           <BuilderClass 
className="org.opensaml.xacml.ctx.impl.StatusMessageTypeImplBuilder" />
           <MarshallingClass 
className="org.opensaml.xacml.ctx.impl.StatusMessageTypeMarshaller" />
           <UnmarshallingClass 
className="org.opensaml.xacml.ctx.impl.StatusMessageTypeUnmarshaller" />
       </ObjectProvider>
      
       <!-- StatusMessageType -->
       <ObjectProvider qualifiedName="xacml-context:StatusMessageType">
           <BuilderClass 
className="org.opensaml.xacml.ctx.impl.StatusMessageTypeImplBuilder" />
           <MarshallingClass 
className="org.opensaml.xacml.ctx.impl.StatusMessageTypeMarshaller" />
           <UnmarshallingClass

       </ObjectProvider>
