[lib.locale.codecvt.virtuals] is 22.2.1.5.2 in the 2003 standard. It=20
moved to 22.2.1.4.2 in the current working draft.

In general, references to the working draft should be by the label and=20
not by [sub]section numbers. Those numbers will change as things are=20
added or modified. The labels will stay the same.

Well, almost the same: the initial "lib." is about to go away. That=20
makes it much easier to find things in an alphabetical list that maps=20
labels to section numbers, which will be included in the next revision=20
of the working draft.
