Re: [xml-dev] What constitutes an XML document?

Your doc *is* an XML document if it matches to the XML grammar as
defined in XML Spec (http://www.w3.org/TR/2000/REC-xml-20001006):

   document ::=  prolog element Misc*
                 ^^^^^^
   prolog ::= XMLDecl? Misc* (doctypedecl Misc*) ?
              ^^^^^^^         ^^^^^^^^^^^       ^^^
            <?xml ...?>       <!DOCTYPE ...>     |
                                                 |
                                                 |
                                                 |_>  means that

doctypedecl may appear one time, but must NOT: thus

<?xml version="1.0"?> 
<greeting>Hello, what are the news from your agency ?</greeting>

is a $genuine$ XML document.

Bye :-)
