  It's not at all clear what conversion is needed.  Do you propose
converting it to a text node and replacing the '<' and '&' characters
with EntityReference nodes?  It sounds to me like the XPath spec is
referring to the serialization format, which is just confusing when
talking about nodes.
  I think adding the CDATA_SECTION_NODE to the nodeType check is
sufficient.  So don't let me stop you!  ;-)
