	No, I'm suggesting that ISP or anyone else that normally
	debugs DNS issues don't need new tools to debug DNSSEC.
	They already have the basic tools they need.

	The original claim was that new tools were needed which I
	disputed.  One can have fancier tools but they are unlikely
	to find things the simpler tools don't.

	Now you can wrap those tools up in a fancy web page if you
	want.  That's all the existing delegation checking web pages
	do.  I also suspect delegation checking web pages will grow
	DNSSEC checks as time goes by.  Some probably already do.

			Id's and algorithms is initially enough,
			though full hashes would be better.
		Valid signature times.
