Good point, the (::) will be needed to prevent the declaration from
looking like  X::itk::ObjectFactory when the Macro is called inside 
any X namespace.

Yes, this is another possibility. But it will be just the same code
that is actually contained in the NewMacro. It is not that they are 
a lot of lines, but the fact that they will be copied exactly in all 
the derived classes.

Derivation from itk classes is one of the typical ways in which the
toolkit could be used and it could be nice to verify that it can be 
done without much difficulty.



Thanks,
