WML Tags and Attributes

Issue 1 April 2005 153

● <head> tag - The <head> tag is an optional WML tag. This tag contains information that

relates to the deck as a whole, including meta-data and access control elements. This tag

is not supported.

● <meta/> tag - The optional <meta> tag is contained between multiple <head> tags. This

tag gives values for the parameters that describe the content of the deck. This tag is not

supported.

● <card> tag - A single WML file can contain multiple cards, supporting the analogy of a

“deck” of “cards” within a single WML file. A card is essentially the specification of one

specific WML page. This is a mandatory tag.

The card element attributes supported by the Web browser are as follows (unsupported

attributes are indicated as such in the Comments column):

Attribute Value(s) Description Comments

newcontext true

false

Re-initializes the

browser context.

Default is “false.”

Clears out the current WML

browser context, which entails

emptying the navigation stack

history and clearing out all

variables. When set to “true” the

browser clears its history buffer

and captures and buffers the

WML card title attribute of the

WML card containing the

newcontext tag. This buffered

attribute is used as the title for

every WML element having a null

or missing title attribute, including

top-level cards. SUPPORTED.

ordered true

false

Specifies the order of

card content. When

ordered is set to “true”

the browser displays

the content in a fixed

order. When ordered is

set to “false” the users

decide the order as

they navigate between

content. Default is

“true.”

Optional. Sets a Boolean value

that provides information on how

the content of the current card is

arranged. Used by the browser to

organize the display presentation

and layout. If set to true, content is

organized in a linear sequence of

elements - for example, a series

of ordered or non-optional input

elements. If set to false, content is

in no natural order - for example, a

series of unordered or optional

input elements. The default is

true. NOT SUPPORTED.

title cdata The title of the card. Can be used for title displays.

SUPPORTED.

onenterbackward url Occurs when the user

navigates into a card by

means of a “prev” task.

SUPPORTED.
