Is this markup an invalid XML element?

<!AFDR "ISO/IEC 10744:1997">

IE 5.x XML parser reject this markup as an invalid element

Declaration has an invalid name. Line 1, Position 3

<!AFDR "ISO/IEC 10744:1997">

I am trying to find something in W3C specs about it but with no sucess. By
the way, what is the official list of valid <!...> markups:

<!DOCTYPE....> ???, <!doctype....> ???, both ????
<!SGML...> ????, <!sgml..> ???, both ???
others ????

In which document is this listed? I know that these are all valid SGML
markup and there is ISO documents on it, but where can I find W3C documents
giving that information?
