I am not sure I understand your question. From the schema you can
see that the Work element is of the GetJobWork type. So there will
be a C++ class Job::v1::GetJobWork.

Also note that in your schema the Work element is inside a choice
compositor. In the C++/Tree mapping this means that the resulting
C++ member will be of the "optional" cardinality. To access such
an element you would need to write something like this:

if (getDetailsRespPtr->Work ().present ())
{
  Job::v1::GetJobWork& w (getDetailsRespPtr->Work ().get ());
}

For more information on different member cardinalities and how to
access them, please read the first two sections in Chapter 4,
"Working with Object Models" in the C++/Tree Mapping Getting
Started Guide:
