 it doesn't. 

libxslt/transform.c: function xsltApplyStylesheetInternal

    if (doc->intSubset != NULL) {
        /*
         * Avoid hitting the DTD when scanning nodes
         * but keep it linked as doc->intSubset
         */

The DTD node is not part of the XPath data model of a document.
the information isn't lost though, that could be recovered, see
the code in question.
