SAXException: PI names starting with 'xml' are reserved.

Question

Has anyone run across a problem trying to parse an xml instance (in this case it's an XSL style sheet) using Oracle's parsers? I'm getting the following sax error message:
SAXException : oracle.xml.parser.v2.XMLParseException: PI names starting with 'xml' are reserved. detailed SAX exception message: PI names starting with 'xml' are reserved.
The code generating this error is:
XMLDocument xml = ParseDocument(xmlDoc, parser);
private static XMLDocument ParseDocument(String documentStream,
DOMParser parser)
XMLDocument returnXML = null;
try
parser.parse(new InputSource(new ByteArrayInputStream(documentStream.getBytes())));
returnXML = parser.getDocument();
catch (SAXException saxE)
System.err.println("SAXException : " + saxE + " detailed SAX exception message: " + saxE.getMessage()); // this is the statement generating the error message
catch (IOException e)
System.err.println("IOEx, Parse failed : " + e);
catch (Exception e)
System.err.println("Ex, Parse failed : " + e);
return returnXML;
Thanks in advance for any help you can provide.
Sincerely,
Tim

lv_clob is invalid, there are two
<?xml version="1.0" encoding="UTF-8"?> elements, remove one of them.
