Because I used two sentences?  Because I didn't start my sentence
with "SCSV means"?

My two sentences describe everything you need to know:

    SCSV absent,  RI absent:   hide the kids
    SCSV absent,  RI present:  same as RI
    SCSV present, RI absent:   same as empty RI
    SCSV present, RI present:  same as RI (SCSV ignored)

Why do you want the last one to be "ABORT!!"?
