F66: Failure of Success Criterion 3.2.3 due to presenting navigation links in a different relative order on different pages
Important Information about Techniques
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.
Applicability
Applies to all technologies

Description
This describes a failure condition for all techniques involving navigation mechanisms that are repeated on multiple Web pages within a set of Web pages (Success Criterion 3.2.3). If the mechanism presents the order of links in a different order on two or more pages, then the failure is triggered.
Examples
Failure Example 1: An XHTML menu presenting a series of links that are in a different relative order on two different pages
Examples of a navigation mechanism that presents links in a different order.
Page 1 Menu
Example Code:
<div id="menu">
<a href="Brazil.htm">Brazil</a><br />
<a href="Canada.htm">Canada</a><br />
<a href="Germany.htm">Germany</a><br />
<a href="Poland.htm">Poland</a>
</div>
Page 2 Menu
Example Code:
<div id="menu">
<a href="Canada.htm">Canada</a><br />
<a href="Brazil.htm">Brazil</a><br />
<a href="Germany.htm">Germany</a><br />
<a href="Poland.htm">Poland</a>
</div>

Procedure
Check to see if a navigation mechanism is being used on more than one Web page.
Check the default presentation of the navigation mechanism on each page to see if the list of links are in the same relative order on each Web page.
Note: "Same relative order" means that secondary navigation items may be in between the link items on some pages. They can be present without affecting the outcome of this test.
Expected Results
If #1 is true and #2 is false, then this failure condition applies and content fails the Success Criterion.
