Multiple titles

It can be very useful to attach a title to each participating resource when these resources are not mentioned individually in the document text. It is also possible to give each resource multiple titles.

Titles as selection text

In the example above, each linked resource is referred to in the text, and these references are treated as labels by enclosing them in LocalResource and RemoteResource elements. Typically, users would follow a specific link simply by selecting the appropriate reference text. But this approach cannot work when one or more of the targeted resources is not mentioned in the text at all. The Title attribute can be used to overcome this problem:

<para>... and the quote 'not tonight Josephine' is
attributed to
<extendedLink>
  <localResource>Napoleon</localResource>
  <remoteResource xlink:title="Campaigns"
                  xlink:href="..." />
  <remoteResource xlink:title="Life Story"
                  xlink:href="..." />
  <remoteResource xlink:title="Famous Generals"
                  xlink:href="..." />
  <remoteResource xlink:title="French Law"
                  xlink:href="..." />
  <remoteResource xlink:title="Delusions"
                  xlink:href="..." />
</extendedLink>.</para>

These descriptions may be presented in a selection window:

The same Title attribute can be used on simple links, and on arcs (explained below).

Title elements

It is also possible to designate entire elements as title-type elements, and to use these elements within the other elements that take the roles of extended link, locator and arc structures. Indeed, any one of these objects can contain multiple title elements, with each one perhaps containing the same text, but in a different language (using the xml:lang attribute to identify the language concerned). While it is possible for each of these constructs to contain both a Title attribute and one or more Title elements, the draft standard does not suggest any particular significance to such combinations.

<remoteResource ...>
  <resourceTitle xlink:type="title" xml:lang="...">
    ...
  </resourceTitle>
  <resourceTitle xlink:type="title" xml:lang="...">
    ...
  </resourceTitle>
</remoteResource>
