/**
* Returns the result of an XSL Transformation as a JDOM document.

* <p>If the result of the transformation is a list of nodes, this method attempts to convert it

* empty list.
*
* <p><strong>Warning</strong>: The XSLT 1.0 specification states that the output of an XSL
* transformation is not a well-formed XML document but a list of nodes. Applications should thus
* use {@link #getResult} instead of this method or at least expect <code>null</code> documents to
* be returned.
*
* @return the transformation result as a JDOM document or <code>null</code> if the result of the
* transformation can not be converted into a well-formed document.
