| Note | If both when and dur or dur-iso are specified, the
            values should be interpreted as indicating a span of time by its starting time (or date)
            and duration. In order to represent a time range by a duration and its ending time the
                when-iso attribute must be used. In providing a ‘regularized’ form, no claim is made that the form in
            the source text is incorrect; the regularized form is simply that chosen as the main
            form for purposes of unifying variant forms under a single heading.  | ||||||
