+/**
+    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>
