Verification was done against BrokerN 01f

>Section 3. Terminology and Concepts -> various specs
>- Situation, NotificationMessage, Notification, NotificationProducer,
NotificationConsumer, Subscription, SubscriptionManager, Subscriber
> WS-BaseN

   Observation: NotificationMessage from whitepaper morphed into
   Notification (I think this is correct)
   Observation: Subscription is different from whitepaper but is in line
   with Issue 2.23 resolution (I think it is correct)
   Observation: SubscriptionManager is different from whitepaper but is in
   line with issue 2.23 resolution ( I think it is correct)

   Verified: All other terminology copied from whitepaper is the same

>- Topic, TopicSpace, TopicTree -> WS-Topics

   Issue: No terminology defined in Topics for Topic, TopicSpace, TopicTree

>- NotificationBroker, Publisher, PublisherRegistration,
PublisherRegistrationManager, Demand-BasedPublisher -> WS-BrokeredN

   Issue: BaseN morphed NotificationMessage term into Notification.
      Publisher term refers to NotificationMessage.  Need to change
      NotificationMessage to Notification or change BaseN from Notification
      to NotificationMessage
      NotificationBroker term refers to NotificationMessage.

   Observation: PublisherRegistration different from whitepaper.  Change in
      line with Issue 2.23 resolution.
   Observation: PublisherRegistrationManager changed in line with Issue
      2.23 resolution.

   Issue:  PublisherRegistration and PublisherRegistrationManager may be
      inconsistent
   PublisherRegistration says:
      PublisherRegistration resources are manipulated by messages sent to a
PublisherRegistrationManager Web service.
   PublisherRegistrationManager says:
      A publisher registration resource can be manipulated through
PublisherRegistrationManager message exchanges.

   Nit: Demand-BasedPublisher use of contraction "doesn't" should be "does
   not"


> Section 5. Security Considerations -> WS-BaseN and WS-BrokeredN (with a
little wordsmithing to tailor to each spec).

   BaseN
      Verified: Security considerations from whitepaper (with some
      wordsmithing) has been integrated
   BrokerN
      Verified: Security considerations from whitepaper (with some
      wordsmithing) has been integrated
