Activated

TBD: define as click or relevant keypress like Enter/Return, and spacebar in some scenarios.

Assistive Technology

TBD

Default Behavior

TBD

Marked Element(s)

TBD. At Risk. Will be defined in conjunction with markrequest, which is covered by ACTION-25, and not yet in the spec.

Point-of-Regard

UIRequestEvents initiate from the element representing the point-of-regard, and are referenced in the Event object's target property.

For mainstream user agents, the point-of-regard will likely be the element under a pointer (e.g. mouse cursor) or, in the case of keyboard events, the currently focused element (e.g. document.activeElement). Assistive technologies or other alternative inputs may determine another element to be the subject of the user's attention, and initiate events from this new point-of-regard.

Still looking for a better term than point-of-regard.

Reflected Attribute

Attributes whose DOM property and content attribute values remain in sync. Identical to reflected attributes in HTML.

Request Event Receiver

The closest DOM ancestor to the user's point-of-regard that declares the current event type via the uiactions content attribute or uiactions DOM attribute. The Request Event Receiver is referenced in the Event object's receiver property.

UI Request Events are not initiated by the user agent unless the following are true:

1. The user's point of regard is on the current or descendant node of an element that declares the event receiver via @uiactions
2. The event receiver node (or any ancestor node of the receiver) also registered as the event listener via element.addEventListener()

Some of this definition will need to be massaged and move into the normative sections above defining @uiactions.

User Agent
