NAME
	to_dtd_unq - serialize the UNQable object into a data structure

PROTOTYPE
	mixed *to_dtd_unq(void)

CALLED BY
	Anybody

DESCRIPTION
	Serialize the object to the equivalent of DTD-parsed UNQ.  This
	object has a default stub that causes an error, so you'll need
	to implement it if you want it.  For more about the format of
	preparsed UNQ, see parse_to_dtd in the UNQ_DTD object.

	This function isn't access-protected.  You should access-protect
	your version of this and all other inherited functions, including
	upgraded() and destructed().

RETURN VALUE
	Nothing.

ERRORS
	Usually none.
