See Understanding Techniques for WCAG Success Criteria for important information about the usage of these informative techniques and how they relate to the normative WCAG 2.0 success criteria. The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2.0.
Any technology containing text.
This technique relates to:
The objective of this technique is to provide a definition for any word used in an unusual or restricted way.
A word is used in an unusual or restricted way when:
dictionaries give several definitions of the word but one specific definition must be used in order to understand the content;
a specific definition must be used in order to understand the content and dictionaries list that definition as rare, archaic, obsolete, etc.;
the author creates a new definition that must be used in order to understand the content.
This technique can also be used to provide definitions for jargon, that is, the specialized vocabulary used in a particular profession or technical field and understood by people in that field but not by people outside the field.
The technique can also be used to define idiomatic expressions. For example, speakers of a language who live in a particular region may use idiomatic expressions that are accepted by everyone in the region but not by people from other regions where the same language is spoken.
The word "technology" is widely used to cover everything from the stone tools used by early humans to contemporary digital devices such as cell phones. But in WCAG 2.0, the word technology is used in a more restricted way: it means a mechanism for encoding instructions to be rendered, played or executed by user agents, including markup languages, data formats, and programming languages used in producing and delivering Web content.
The word "ether" is defined as a substance that filled interplanetary space: "He believed that sound traveled through the ether."
The word "driver" is defined as software that contains specific instructions for a printer: "It may be necessary to update the driver for your printer."
Some people say "spill the beans" when they mean "reveal a secret", e.g., "In the police station, Joe spilled the beans about the plot to kidnap the prime minister."
This example uses parentheses to provide the definition of an idiomatic expression in Japanese. The phrase in Japanese says that "he throws a spoon." It means that there was nothing he can do and finally he gives up.
さじを投げる(どうすることもできなくなり、あきらめること)。
Users may not understand the meaning of an unfamiliar word adopted from another language: "We need to leave town pronto (quickly).
In Japanese, Kata-kana is used for adopted foreign words. If words are unfamiliar to users, provide the meaning or translation so that users can understand them.
アクセシビリティ(高齢者・障害者を含む全ての人が利用できること)は、Webサイトに不可欠である。
English translation: "Accessibility" (it can be accessed by all users including elderly people and people with disabilities) is an essential aspect of the Websites.
レイアウトテーブルとCSSの併用をハイブリッド(複合型)という。
English translation: Using both layout table and CSS is called "hybrid" (combination of multiple forms).
No resources available for this technique.
For each word or phrase used in an unusual or restricted way:
Check that a definition is provided for the word or phrase
Check #1 is true.
If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been satisfied in some other way, only that this technique has not been successfully implemented and can not be used to claim conformance.
