Is this invalid?

Hi Chris,

Unless I am missing something here, the answer is really obvious - in
the XML specification.

I presume you mean something more complicated?

Steve Newcomb gave me a good answer about the <!AFDR "ISO/IEC 10744:1997">
markup. And I should thank him for giving this information. I didn't knew
the origin of this markup and encountered it often for Hytime documents. I
thought that this was transfered to XML because XML is supposed to be a
subset of SGML. But Steve brought the information that this markup is not
even a SGML standard because it is not yes part of the SGML new spec. So,
let's put that in the perspective that's its a common practice but not yet
part of a published standard.

About the uppercase lowercase for prolog declarations I finally found the
clause specify uppercase by example like in the following clause:
[52]  AttlistDecl ::=  '<!ATTLIST' S Name AttDef* S? '>'
[53]  AttDef ::=  S Name S AttType S DefaultDecl
I got some doubt after being argued that these reserved keyword should be
uppercase and lowercase, my parser only accept uppercase. I am reassured
now, the parser is OK.
