Yes of course you can, but then you have to extract the xquery out of
the xml document to give it to an XQuery processor, so that is just
saying that any string can be placed in an XMl document so long as XML
syntax is quoted. It still means that Xquery gains nothing from XML.


If Xquery is designed to be used in that way, why does it use
syntax like <aaa> .. </aaa>, or &#xe9; that is designed to look like XML
but which if used quoted in an XML document doesn't look so much like
XML at all? If the XML Query processor was expecting an XML document
rather than a string to be extracted out of your XML document example
the XML syntax that appears in the XML query would be encoded in the XML
document as XML constructs not just some big cdata section or a mass of
&lt;.
