+/**
+ A wrapper of I18N wrappers. Using this is more expensive than using some
+ single wrapper classes so use it only if you must pass a single pointer
+ without knowing in advance what is needed, e.g. for
+ SfxPoolItem::GetPresentation(). Remember that this wrapper was only created
+ for convenience to bypass some oddities, if possible don't use it. <p>
+
+ Implemented are only the const get...() methods of the wrappers, which are
+ loaded on demand, for consistency reasons no change of locale is possible.
+ Only default calendar and default collator are supported. <p>
+
+ One exception though is the calendar wrapper: to be able to set a value and
+ retrieve calendar values it is not const, so methods using this should
+ reset the calendar to the previous value if it isn't sure where the
+ IntlWrapper did come from. <p>
