   }

Notes
-----
The entries in the mplsXCTable are indexed by {mplsXCIndex, mplsXCInSegmentIndex, mplsOutSegmentIndex}. All XC entries for the same LSP should share a common value of mplsXCIndex because mplsTunnelXCPointer can be set to point to the first entry and then all of the other entries can be found.

The error in the example in Section 6 is that it shows a different value of mplsXCIndex for the reverse direction cross-connects. It should be set to the same value as is used for the forward direction cross-connect.
