It seems that when we (generally) discuss actors, we are concerned with an
actor-endpoint relationship and only the header-actor relationship as a
derivative of the aforementioned.

I think you need to define a uri-list of actors valid for an endpoint that
apply to all headers at said endpoint.  I believe it is safe to assume that
>  1 actor can exist per endpoint.

It the above is correct, then the issue is where!  If you define a uri-list
of actors on soap:header then any wsdl:port linked to the binding where the
soap:header resides would have to inherent those actors, which effectively
makes the actor(s) specific to the header and not the endpoint.

So would...

<wsdl:service...> 
	<wsdl:port...> 
		<soap:address location="some-uri"> 
			<soap:actor actors="uri-list"/> 
		</soap:address> 
	</wsdl:port> 
</wsdl:service> 

be more efficient? You could then change the valid actors for an endpoint
and have reuse available on the bindings.

Thx,
