No idea why but it is the same in delphi < d2010. Probably in d2010 it 
depends on project rtti settings. And UnitName = '' in d2009 for classes 
with no RTTI.

Probably no way except the using the same info which ClassType using.

Still the question. Using RTTI and return empty result if it does not 
exists or changing the compiler to write unit name near the class name?
