EDOC — Chapter 3, Section 4.1.4.4 "Notification" pg 226, 227

It's not explained clearly what is in the PubSubNotice and what is in
the EventNotice. i.e. a bullet list of data to be included in an
EventNotice is given on page 227, but some of this may be included in
every PubSubNotice (EventNotice's supertype). Both of these types are
simply Attribute collections (CompositeData). 4.2.2.4 "EventNotice"
gives no information about how this information is transmitted.

Also: 4.2.2.4 "Related Elements" also wrongly includes inheritance.

Suggested Resolution: Clarify what data is included in a PubSub notice,
and what is only in its subtype, EventNotice, and how. (In 4.2.2.4)
Perhaps we even need some specific attributes to standardise the names
and types of the data that are given in the bullet list of pg 227.
