Minor changes in (new) Section 8.3.5 Business Event
For better readability:
From "A business event represents a business-related state change." to "A business event represents something that happens or occurs in the business, especially something significant or noteworthy, such as a business-related state change."
From "...denotes the moment or moments at which the event happens" to "...denotes the moment or moments at which the event happens, or its frequency"
From "A business event may trigger or be triggered (raised) by a business process, business function, or business interaction." to "A business event may trigger or be triggered (raised) by internal and external business behavior."
