 An optional name member is associated with a wxVariant. This might be used, for example, in CORBA
 or OLE automation classes, where named parameters are required.
 
-wxVariant is similar to wxExpr and also to wxPropertyValue. However, wxExpr is efficiency-optimized for
-a restricted range of data types, whereas wxVariant is less efficient but more extensible.
-wxPropertyValue may be replaced by wxVariant eventually.
