XML in a Nutshell, 3rd Edition

Title Elements

As you’ve seen, extended link elements, locator elements, arc elements, and resource elements can all have xlink:title attributes that provide a short blurb of text identifying the link. However, this isn’t always enough. For instance, in a document that was a rather large extended link, you might want to mark up the titles using XHTML or some other vocabulary. To this end, a title can instead (or in addition) be provided as a title type child element, that is, an element whose xlink:type attribute has the value title.

For example, suppose you wanted to provide a more complete description of each edition of The Wonderful Wizard of Oz than simply who published it. Then you would give the edition element a title type element containing any convenient markup, like this:

<edition xlink:type="locator" xlink:href="urn:isbn:0700609857"
         xlink:title="University Press of Kansas"
         xlink:role="http://purl.org/dc/elements/1.1/identifier"
         xlink:label="ISBN0700609857">
  <publisher_info xlink:type="title">
                  <ul>
                  <li>The Kansas Centennial Edition</li>
                  <li>Illustrated by Michael McCurdy</li>
                  <li>Foreword by Ray Bradbury</li>
                  <li>1999</li>
                  <li>216 pages</li>
                  <li>SRP: $24.95</li>
                  </ul>
                  </publisher_info>
</edition>

What markup you use inside the title element is up to you as long as it’s well-formed XML. XLink doesn’t constrain it in any way; how the application interprets that markup is its own business. Here we’ve used basic HTML that a browser might perhaps be able to render. Once again, ...
