Attached is an example of how do do this.  Drawback: the
TCPositionTraits object now has a lot of typing in it.  And if/when
you create another object (e.g. TCEmployeeTraits) you are going to
have to do a lot of typing again.  There will be a lot of code
duplication.
Attached is a version that eliminates the code duplication.  Drawback:
it's now a mess of templates and specializations.
One more thing that would make this look
a bit better:

... mItems = {
  makeItem(&TCPosition::mLatitude, TCPosition::sLatitudeTraits),
  ...
};

makeItem is a pretty simple function template.
