Hi Peter:

I noticed that draft-ietf-lsr-flex-algo-07 adds exclude SRLG TLV. SRLG defines 
a group of risk-sharing link groups. It is generally used to prevent the 
primary and standby paths from passing the same risk-sharing link group .I 
don't know why a group of SRLG links should be excluded from the FlexAlgo 
calculation. What is its usecase?
