Notes:
WML supports the notion of variables stored on the browser. These variables can be set and referred to in any WML card. To refer to a variable that’s already set, use $name or $(name).
onevent allows associating certain actions with the enclosing element. The possible types of the onevent element are onenterforward and onenterbackward.
If refresh has any side effects on the browser state that are visible to the user, the user browser will update them. This may happen if the card being displayed shows the value of a variable which happens to be modified during refresh.
