Yes, factory is now a reserved word in CORBA 2.3. It's used by objects
by value. In your example above, you can simply change "factory" to
any other name, since the name of a parameter is not significant. In
the case of IDL like

  interface factory { ... };

where the name "factory" is important, you can prefix the name with an
underscore like

  interface _factory { ... };

which is treated exactly as if you had written just "factory", except
that it isn't checked for keyword clashes. With the new underscore
escapes, you can do ghastly things like

  interface _long { ... };

which declares a new interface named "long"!  Don't do that!

omniORB does not yet support wstring. No version ever has.

Cheers,
