Subject: Parsing XML from a CDATA Structure

Using Saxon 8, I am attempting to parse an XML string from within a CDATA
Structure.
Using the saxon:parse extension I have been able to do this, except when the
xml string includes the following tag at the beginning of the string.
<?xml version="1.0" encoding="UTF-8"?>
I am getting the following error
net.sf.saxon.xpath.DynamicError: org.xml.sax.SAXParseException: The
processing instruction
target matching "[xX][mM][lL]" is not allowed.
Transformation failed: Run-time errors were reported
The sample xsl file will succesfully parse the xml file if I remove the
string from the cdata structure.
I don't control the structure of the XML, so I do not have the ability to
somehow strip out the ?xml string.
Is there any way to have Saxon ignore this string.
