# by default, event sent to MB via sendMB

# event not sent to GA.

# for GA, add event-tracking-ga attribute, where the value is the GA category
|
|
# Either GA or MB can use the attribute event-tracking-send-once='true' to
|

# send event just once

# MB will use the key and GA will use the action to determine if the event

# has been sent
