|Event type: (From DOM Level 2 Events)|
|Event target element: form control, possibly other elements such as hyperlinks|
DOMActivate is probably the event most commonly used by XForms authors. Activation in this context can mean a mouse click, pressing the Enter key, or any other action indicating the user has requested that something special should happen.
Even though a DOM isn't guaranteed to be present in an XForms engine, this event will always work as described here.
