	    <para>This template marks the current object with a <literal>

		<literal>id attribute</literal> is used to generate the label.
		In this sense, in most cases its the current node itself.
		If the used object has not an id attribute, a unique id is
		obtained by means of the <literal>generate-id</literal> function.
		Moreover, if we are using the hyperref package, a hypertarget is
		also defined for this object. </para>
