A broadcaster is used when you want multiple elements to share one or more attribute values, or when you want elements to respond to a state change. Any elements that are observing the broadcaster will share the attributes placed on the broadcaster. For instance, if the broadcaster has a
label attribute, the observers will use that label. If the label changes, the labels of the observers will update automatically. An
onbroadcast event will be sent to the observers when a change is made.
More information is available in the Broadcasters and Observers XUL Tutorial.
