WML Tags and Attributes

Issue 1 April 2005 169

Variable Elements

● <setvar> tag - There are no visual rendering implications with this tag.

● <timer> tag - The timer tag sets a timer that starts counting. This tag must be used with

<onevent type=”ontimer”> to be useful. The Web browser sets the timer value to 10 or to

the value set in the <timer> tag, whichever is greater. A minimum setting of 10 equates to

a minimum timer setting of one second.

Character Entities

As with any syntactic language, WML has certain characters that have special meaning. The

two most obvious of these characters are the < and > symbols, which surround all tags. These

characters cannot be typed in directly if the designer's intent is to display these characters.

Thus, all characters that can be displayed in a Web browser have numeric values assigned to

them. The numeric values are entered into the source Web page as &#nnn; where nnn is a

three-digit value. For example, the < symbol is entered as '<'.

In addition, many of these characters also have names assigned. Name values are entered into

the source Web page as &name; where name is the WML name associated with this character.

For example, the < symbol would be entered as '<'. The set of characters defined by the

World Wide Web Consortium are fully supported in the Web browser in conformance with the

standard.
