xml prolog - what am I missing?

[Chris Bentley <chris@webx.com.au>]

Hi, I'm  confused can some put me right;

I keep seeing references alluding to the fact that a document type 
declaration IS NOT part of an XML prolog.
e.g., http://tantek.com/XHTML/Test/minimal.html amongst others.

My confusion comes from my reading of the XML 1.0 spec
"prolog  ::=   XMLDecl? Misc* (doctypedecl Misc*)?"
http://www.w3.org/TR/2004/REC-xml-20040204/#sec-prolog-dtd

..doesn't this mean that a document type declaration IS part of an XML 
prolog?

TIA,
Chris Bentley
