+ *
+ *      - only exposed params are those defined in the OSGi spec. Jetty is
+ *        very tunable via params, some of which it may be useful to expose
+ *
+ *      - no cacheing is performed on delivered resources. Although not part
+ *        of the OSGi spec, it also isn't precluded and would enhance
+ *        performance in a high usage environment. Jetty's ResourceHandler
+ *        class could be a model for this.
+ *
+ *      - scanning the Jetty ResourceHandler class it's clear that there are
+ *        many other sophisticated areas to do with resource handling such
+ *        as checking date and range fields in the http headers. It's not clear
+ *        whether any of these play a part in the OSGi service - the spec
+ *        just describes "returning the contents of the URL to the client" which
+ *        doesn't state what other HTTP handling might be compliant or desirable
