/**
* {@code EndpointMapping} implement that adds SOAP actors or roles to a delegate endpoint. Delegates to another
* {@code EndpointMapping}, set by {@code delegate}, and adds the actors or roles specified by
* {@code actorsOrRoles}.
*
* <p>This endpoint mapping makes it possible to set actors/roles on a specific endpoint, without making the all endpoint
* mappings depend on SOAP-specific functionality. For normal use, setting an actor or role on an endpoint is not
* required, the default 'next' role is sufficient.
*
* <p>It is only in a scenario when a certain endpoint act as a SOAP intermediary for another endpoint, as described in the
* SOAP specificication, this mapping is useful.
