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 in context for any word used in an unusual or restricted way. The definition is provided in the text, either just before or just after the word is used. The definition may be included in the same sentence as the word that is being defined, or in a separate sentence.
He believed that sound traveled through the ether, which was thought to be a substance that filled interplanetary space.
It may be necessary to update the driver for your printer (the driver is software that contains specific instructions for your printer).
Definition: The key words "must", "must not", "required", "shall", "shall not", "should", "should not", "recommended", "may", and "optional" in this specification are to be interpreted as described in RFC 2119.
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）。
No resources available for this technique.
For each word or phrase used in an unusual or restricted way:
Check that the word is defined in text either before or after the first occurrence of the word.
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.
