 * section 11.1 of the XSLT 1.0 Recommendation.  If the argument is a

 * a node-set consisting of a single root node with a single text node
 * child that is the result of calling the XPath string() function on the
 * passed parameter.  If the argument is anything else, then a node-set
 * is returned consisting of a single root node with a single text node
 * child that is the result of calling the java <code>toString()</code>
 * method on the passed argument.
