/**
 * Handler for the Anchor Namespace.
 *
 * This namespace maintains an anchor database, a database of
 * named links. These links can be referenced using the iref
 * tag within this namespace.
 *
 * This allows for a central storage of links, changing links
 * need only be changed in one locations. Designers can reference
 * the link through the symbolic name.
 *
 * Example:
 *
 * <code>
 * <?php
 * $n = XML_Transformer_Namespace_Anchor;
 * $t->overloadNamespace("anchor", $n);
 *
 * $n->setDatabase(
 * array(
 * "pear" => array(
 * "href" => "http://pear.php.net",
 * "title" => "PEAR Homepage"
 * )
 * )
 * );
 * ?>
 * The <anchor:iref iref="pear">PEAR Homepage</anchor:iref> is now online.
 * </code>
 *
 * Output:
 *
 * <code>
 * The <a href="http://www.pear.net" title="PEAR Homepage">PEAR
 * Homepage</a> is now online.
 * </code>
