Question about gmpls-recovery-terminology draft

[takao.okamawari@bt.com]

Think about the following scenario.

A  *-------------* B
   |             |
C  *-------------* D
   |             | 
E  *-------------* F

Two working paths are established between A-B and E-F.
The protection path for A-B is A-C-D-B.
The protection path for E-F is E-C-D-F.
Since the two working paths are disjointed,
the protection resource between C and D is common, 
i.e. shared by two working paths.

My question is where does this protection/restoration method 
fit in the gmpls-recovery-terminology document?
