WML Document Skeleton

Certain tags define the basic framework of a WML document. The tags listed below make up the basic skeleton of a WML document, and are supported by the 4620 unless otherwise indicated.

Common tag attributes: xml:lang, class, and id.

The attributes xml:lang, class and id are universal attributes associated with every WML element.

The web browser will support these tags as follows:


Attribute	Comments
xml:lang	NOT SUPPORTED
class	NOT SUPPORTED
id	SUPPORTED

<wml> tag - The <wml> tag defines a deck of cards and encloses all information the deck and is a required WML element. This tag must contain at least one <card> tag.

<head> tag - The <head> tag is an optional WML tag containing information relating to the deck as a whole, including meta-data and access control elements. This tag is not supported.

<card> tag - A single WML file can contain multiple cards. This leads to the analogy - 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. This entails emptying the navigation stack history and clearing out all variables. NOT SUPPORTED
ordered	true false	Specifies the order of card content. When ordered is set to "true" the browser will display the content in a fixed order. When ordered is set to "false" the users will 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 using a “prev” task	SUPPORTED
onenterforward	url	Occurs when the user navigates into a card using a “go” task	SUPPORTED
ontimer	url	Occurs when a “timer” expires	SUPPORTED

<template> tag - The <template> tag defines a template for all the cards in a deck. The “code” in the <template> tag is added to each card in the deck. Only one <template> tag for each deck may be specified. This tag can only contain <do> and <onevent> tags.

The template tag attributes supported by the 4620 web browser are as follows:


Attribute	Value(s)	Description	Comments
onenterbackward	url	Occurs when the user navigates into a card using a “prev” task	SUPPORTED
onenterforward	url	Occurs when the user navigates into a card using a “go” task	SUPPORTED
ontimer	url	Occurs when the “timer” expires	SUPPORTED


NOTE:	The implication for rendering WML pages is that the local environment will always override a global template for <do> types with the same name and type. If there is a onevent in the template and a local onevent of the same type, the local onevent takes precedence over the global one.

<access> - The <access> tag limits access within the deck to certain cards. This tag is not supported.
