The Prolog consists of an XML declaration, followed by a DTD declaration, followed by a series of processing instructions.

The XML declaration is either

<?<SP>XML<SP>version="1.0"<SP>encoding="UTF-8"?>

or

<?<SP>XML<SP>version="1.0"<SP>encoding="Shift_JIS"?>

The DTD declaration is

<!DOCTYPE<SP>TTMAKER<SP>SYSTEM<SP>"ttmaker60.dtd">
