++ manakai/lib/Message/URI/ChangeLog	22 May 2007 11:23:13 -0000
	* URIReference.pm: Now this module defines a
	class |Message::URI::URIReference| as well as
	a method addition to |Message::DOM::DOMImplementation|.
	It no longer depends on |Message::DOM::DOMCore|.
	(get_iri_reference_3987): Don't use |chr|, use |pack|
	instead, to avoid a byte string is eventually converted to
	a utf8 string.
