■ <do> tag - The <do> tag is a card-level user interface. It serves as a general mechanism for
the user to activate a task, typically performed by the user clicking on 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 4620 web browser does not recognize the specified type, (e.g., testing,
experimental, and vendor specific types), the specified type is treated as unknown. The browser
only renders WML 1.2 tags. Any other tags will cause an error and the user will receive an error
statement "not a valid wml page".
