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.
HTML and XHTML
This technique relates to:
The objective of this technique is to provide expansions or definitions for
abbreviations by using the abbr element
It is always appropriate to use the abbr element for any abbreviation,

<p>Welcome to the <abbr title="World Wide Web">WWW</abbr>!</p> Example Code:
<p>Tasini <abbr title="and others">et al.</abbr> <abbr title="versus">v.</abbr>
The New York Times <abbr title="and others">et al.</abbr> is the landmark lawsuit
brought by members of the National Writers Union against ......</p> Example Code:
<p>The use of <abbr title="Keep It Simple Stupid">KISS</abbr> became popular in ...</p>
Example Code:
<p><abbr title="World Wide Web">WWW</abbr></p>Resources are for information purposes only, no endorsement implied.

abbr.
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.
