Can I remind you that I proposed the reserved word "classified" for this
purpose some while back. It has a few, but helpful, advantages.
	1) It is an adjective.
	2) It implies that the thing is not quite a genuine class, as
	understood elsewhere, but is clearly related.
	3) It carries a feeling that something special has been done to
	values of that type (such as adding a tag, or 'classification') to
	them, without actually ramming the idea down your throat as "tagged"
	does.
