HTML and XHTML
This technique relates to:
The objective of this technique is to describe how the link
element can
provide metadata about the position of an HTML page within a set of Web pages or can
assist in locating content with a set of Web pages. The value of the rel
attributes indicates what type of relation is being described, and the href
attribute provides a link to the document having that relation. Multiple
link
elements can provide multiple relationships. Several values of
rel
are useful:
Start: Refers to the first document in a collection of documents.
Next: Refers to the next document in a linear sequence of documents.
Prev: Refers to the previous document in an ordered series of documents.
Contents: Refers to a document serving as a table of contents.
Index: Refers to a document providing an index for the current document.
A Web page for Chapter 2 of an on-line book might contain the following links
within the head
section.
Example Code:
<link rel="Contents" href="Contents.html" title="Table of Contents" />
<link rel="Index" href="Index.html" title="Index" />
<link rel="Prev" href="Chapter01.html" title="01. Why Volunteer?" />
<link rel="Next" href="Chapter03.html" title="03. Who Volunteers?" />

Use <link>s in your document from W3C's Quality Web Tips
LINK - Document Relationship from Web Design Group
For a Web page that is within a sequence or collection of Web pages:
Check that all link
elements pertaining to navigation occur in the
head
section of the document.
For each link
element in the head
section of the
document which pertains to navigation, check that it contains at least:
a rel
attribute identifying the link type
a valid href
attribute to locate the appropriate resource
All of the checks above are 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.
Techniques are informative—that means they are not required. The basis for determining conformance to WCAG 2.0 is the success criteria from the WCAG 2.0 standard—not the techniques.
