I think we need to allow for the possibility that successful accomplishment 
of multiple techniques may be a way of meeting a particular SC.   Also, 
isn't it true that the techniques are non-normative (not "required" - re: 
abstract in [1]), whereas the SC are normative, so if true I just want to 
make sure that this distinction is preserved in the usage document.

Thanks and best wishes
