Events allow for matching intents by event name instead of the natural
language input. For instance, input
<event: { name: "welcome_event", parameters: { name: "Sam" } }> can
trigger a personalized welcome response. The parameter name may be
used by the agent in the response:
"Hello #welcome_event.name! What can I do for you today?".
Optional. The collection of parameters associated with the
event.
