OleVariant is a compiler internal type so there is no definition of it. It
is essentially a Variant that can only contain OLE-compatible data (e.g.
strings only as type BSTR). In addition to that it also supports dynamic
dispatch (though the normal Variant AFAIK supports that as well) which
allows to use it for late binding function calls in context of COM and OLE.
