++ ChangeLog	21 Jul 2008 05:20:07 -0000
	* cc.cgi: Information sections are now handled by WebHACC::Input
	module.  Input objects for subdocuments now owns their
	own subclass.

2008-07-21  Wakaba  <wakaba@suika.fam.cx>

++ html/WebHACC/Language/ChangeLog	21 Jul 2008 05:24:27 -0000
	* Base.pm: Use new method for node links.

	* CSS.pm: Typo fixes.  Pass |input| object as an argument
	to the CSSOM validation not supported error.

++ html/WebHACC/ChangeLog	21 Jul 2008 05:23:21 -0000
	* Input.pm: A new subclass for subdocuments are added.
	Methods for information sections are added (from cc.cgi).

	* Output.pm (code): Support for attributes.
	(script, dt): New methods.
	(node_link): New method (from get_node_link in WebHACC::Result,
	which comes from cc.cgi).

	* Result.pm (add_error): Show some text even if no location
	infomration is available.  Use input object, if available,
	as fallback for location information.
	(get_error_label, get_node_path, get_node_link): Removed.
	The first method is no longer used.  The latters are now
	supported as |node_link| method in WebHACC::Output.
