HTML and XHTML
This technique relates to:
The link element has inconsistent user agent and assistive technology support.
Some user agents provide an optional navigation bar which will display the information specified in the link element. Current versions of the Mozilla and Opera browsers provide this functionality. IE 6.0 and Firefox 1.5 do not offer this feature but it may be available through extensions or add-ons.
See The 'link'-Element in (X)HTML for
more information on browser support for link.
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?" />Resources are for information purposes only, no endorsement implied.

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.
