/**
 * Establish an entityResolver for newly resolved URIs.
 * <p>
 * This is called from the URIResolver to set an EntityResolver on the SAX
 * parser to be used for new XML documents that are encountered as a result
 * of the document() function, xsl:import, or xsl:include. This is done
 * because the XSLT processor calls out to the SAXParserFactory itself to
 * create a new SAXParser to parse the new document. The new parser does not
 * automatically inherit the EntityResolver of the original (although
 * arguably it should). Quote from JAXP specification on Class
 * SAXTransformerFactory:
 * <p>
 * {@code If an application wants to set the ErrorHandler or EntityResolver
 * for an XMLReader used during a transformation, it should use a URIResolver
 * to return the SAXSource which provides (with getXMLReader) a reference to
 * the XMLReader}
