ITCR — _this for skeleton, not for implementation

_this() method example should be given for the skeleton (eg. A_skel), not for implementation (A_impl):

// C++
class A_skel
: public virtual PortableServer::Servant

Correct code example for _this

The code example defines the _this in the wrong class, it should be done in the skeleton class, not in the user implementation class. Because the example inheritance of the skeleton classes is up to the vendor also the inheritance of CORBA::servant_traits<A>::base_type should be removed and replaced with three dots. As last is the override something that should be removed.
