 * For the first throw, the content remains very simple. We support the 4 modes:
 * start - the initial content is used. first - the first value set in this page
 * is used (else the initial content) last - the last value is used. last-except
 * - the last value is used on the next page. (Contrary to the specification, we
 * fall back to the start-value instead of using an empty value).
 *
 * The string store is used for all counter, counters and string properties.
