I think that's incorrect.

This should be resolved as per:

    if defined(R.scheme) then
       T.scheme    = R.scheme;
       T.authority = R.authority;
       T.path      = remove_dot_segments(R.path);
       T.query     = R.query;
    else
       (left out)
    endif;

    T.fragment = R.fragment;

thus to

    http://2.example.org#frag2
