Event Elements
● <do> tag - The <do> tag is a card-level user interface. It serves as a general mechanism to
activate a task, usually performed by the user clicking a word or phrase in the display. A
task is performed in response to an event. There are four tasks in WML: go, noop, prev,
and refresh.
The mandatory type attribute provides information about the intent of the element, helping to
improve processing. If the Web browser does not recognize the specified type, the specified
type is treated as unknown. For example, testing, experimental, and vendor specific types
would be unknown. The browser only renders WML 1.2 tags. Any other tags cause an error and
the user receives a “not a valid wml page” error statement.
