Notification payload XML
The XML document that defines a toast, tile or badge: its text lines, images, actions and launch arguments, stored in the Notification.Payload column.
A toast payload is a <toast> element with a <visual> / <binding> holding <text> and <image> elements, and optional <actions> with <action> buttons and <input> boxes; the launch attribute carries app-defined arguments. Tiles use <tile> with several bindings, badges a single <badge value> (toast schema). See tables and columns explained.
