All good points.
I'd add that we need better config granularity of the PolicyEngine.
Currently, as I understand it, a PolicyEngine is a Bus extension, so
it's basically 1-1 on a bus. That's fine, as a Bus extension. But
the PolicyEngine also is the place to configure AlternativeSelectors,
which you might prefer to have configurable at endpoint granularity
(or even policy subject granularity, though it's a bit harder to
imagine how that might work).
The same goes for the PolicyInterceptorProviders and the
AssertionBuilders -- these are configured per-Bus, as I understand
it. But we might want finer-grained config in some cases (E.g., use
these policy interceptor providers for these endpoints, those for
another, and yet another set by default).

Hi
CXF WS-Policy framework needs a bit of refactoring. While it's
already quite sophisticated in what it can do, and some of its
features are really cool, like the ability to add JAXB derived
assertions, the ability to attach policy expressions externally and
inline from Spring using WSPolicyFeature, etc, etc, there're few
things which need to be fixed a bit :
* how various policy subjects contribute to corrresponding effective
policies
* how policy alternatives are selected on the server and on the
client (generally a server has to support all the alternatives while
the client can select only a single one)
* automatic policy publication on the server side
* policy engine needs to be enabled by default, etc...
As such some breaking changes to interfaces like EndpointPolicy
(which itself may go in the end, with Policies just keyed by the
type of policy subject), PolicyEngine, may need to be applied. CXF
does not allow for alternative PolicyEngine or EndpointPolicy
implementations be injected anyway. This should not have any adverse
affect on any applications out there, if any, which do rely on
WSPolicy expressions, perhaps those dealing with WS-Addressing or WS-
RM or MTOM...
