* For every one of these WhichIds a static Default must be present in the
* 'pDefaults' array. They start with an SfxPoolItem (with the WhichId
* 'nStartWhich'), are sorted by WhichId and consecutively stored.
*
* 'pItemInfos' is a USHORT array arranged in the same way, which holds
* SlotIds and Flags. These SlotIds can be 0, if the affected Items are
* exclusively used in the Core.
* The flags allow for e.g. enabling value sharing (poolable).
