Set to true to monitor the target node (and, if subtree is true, its descendants) for the addition or removal of new child nodes. The default is false.

@:optionaloptionalcharacterDataOldValue:Null<Bool>

Set to true to record the previous value of a node's text whenever the text changes on nodes being monitored. For details and an example, see /en-US/docs/Web/API/MutationObserver. No default value.
