#### SAMLv2 SOAP Binding

The SAMLv2 SOAP Binding service provides SOAP-based exchange of SAMLv2 Request and Response message between a OpenSSO Client and the OpenSSO Server. The requests received are delegated to the request handler for further processing. The key to the Request Handler and the meta alias is in the SOAP Binding service URL. A mapping of the meta alias and the RequestHandler is stored in the SAMLv2 SOAP Binding service which can be read from the OpenSSO configuration store.

##### Request Handler List

The RequestHandlerList is a list of key/value pair entries containing the mapping of the meta alias to the RequestHandler implementation. This attribute must be set if a OpenSSO 8.0 server is being configured to act as Policy Decision Point (PDP).

The Key is the Policy Decision Point meta alias and the Class is the Java class name, which is the implementation of RequestHandler Interface which can process XACML Requests.

For example, If the meta Alias of the XACML Policy Decision Point is `/pdp` and the implementation of the interface is `com.sun.identity.xacml.plugins.XACMLAuthzDecisionQueryHandler`, then the key should be set to `/pdp` and the class should be set to `com.sun.identity.xacml.plugins.XACMLAuthzDecisionQueryHandler`.
