<title>Parameters</title>
<terms>
<item>
<title><code>$node</code></title>
<p>The <sys>link</sys> or other element creating the link.</p>
</item>
<item>
<title><code>$action</code></title>
<p>The <sys>action</sys> attribute of <code>$node</code>.</p>
</item>
<item>
<title><code>$xref</code></title>
<p>The <sys>xref</sys> attribute of <code>$node</code>.</p>
</item>
<item>
<title><code>$href</code></title>
<p>The <sys>href</sys> attribute of <code>$node</code>.</p>
</item>
<item>
<title><code>$role</code></title>
<p>A space-separated list of link roles, used to select the appropriate title.</p>
</item>
<item>
<title><code>$info</code></title>
<p>An <sys>info</sys> element that overrides the info found in a target node.</p>
</item>
</terms>
</synopsis>
<p>This template outputs a text-only tooltip for a link. If <code>$xref</code> points to a
valid page or section, the text title from that page or section will be used.
If the target does not specify a text title, the primary title is used.</p>
<p>For inline links, <code>$node</code> should be the <sys>link</sys> element. For links from a
<sys>links</sys> element, <code>$node</code> should be that <sys>links</sys> element, or the containing
element when the <sys>links</sys> element is implicit.</p>
<p>This template first calls <code xref="mal.link.tooltip.custom">mal.link.tooltip.custom</code> with the same arguments.
If that template returns a non-empty string, it is used as the return value,
overriding any other behavior of this template.</p>
<p>If only <code>$href</code> is provided, that URL is used as the tooltip. If a target
page or section cannot be found, <code>$xref</code> is used as the text content. Special
tooltips may be provided for certain URI schemes.</p>
<p>Normally, this template automatically looks up information from a targret node
according to the <code>$xref</code> parameter. However, if the <code>$info</code> parameter is given,
information in that node set is used instead. This is useful for external info
links, where the target information is provided as child elements to the <sys>link</sys>
element.</p>
