Notification message schema

The following specification describes the structure of all valid notification messages. This example describes the structure of the messages only. It says nothing about how many elements are in the messages or the order in which they appear. The rules for the number of elements are:
  • One broker element
  • Other elements: zero, one, or more

There are no rules for the order of notification messages.

In this example, <...> denotes an XML element, and ??? indicates where individual class names are allowed:
<Broker identifier label>
