Did u know? What is the Markup Basics?
Markup rules closely follow the same rules of any markup language.

 Should use start and end tags.
 Utilize attributes within tags to control their effect.
 Additional white space is ignored.

There are some variations.
 WML tags and attributes are case-sensitive and MUST be lowercase.
 Syntax must be followed.

Refresh Task

The <refresh> task refreshes some specified card variables. If any of the variables are shown on
the screen, this task also refreshes the screen.

Example: The example below uses an <anchor> tag to add a "Refresh this page" link to
the card. When the user clicks on the link, he or she refreshes the page and the value of the
variable x will be set to 30:
<?xml version="1.0"?>
