CData section not top-level

	In the July 2004 grammar, a CData section apparently is allowed
	only within the content of an element.  This differs from the
	November 2003 version of the grammar where it is allowed
	anywhere an XML element is allowed.  The XQuery:

		<![CDATA[hello]]>

	is now illegal.  Is this the intent or a mistake?
