That's what I thought at first, but the characters with Unicode code 
points 0x01-0x08, 0x0B, 0x0C, 0x0E-0x1F are not permitted *at all* 
in an XML document.  CDATA sections provide for escaping characters 
such as '<' and '&' which might be interpreted as XML markup, but 
that is not the problem here.  See productions [18] - [21] in the 
XML spec (http://www.w3.org/TR/2006/REC-xml-20060816/ sec 2.7).
