[CF-metadata] Question regarding flag_values and flag_masks

Hi.

Is it legal to have a flag value of zero that is associated with a flag
mask? That is to say, is it OK to do something like

     flag_masks = 3b, 3b, 3b, 4b, 4b;
     flag_values = 1b, 2b, 3b, 0b, 4b;
     flag_meanings = "subsystem1 subsystem2 subsystem3 warning failure";

The implication would be that a value of 1, 2, or 3 would indicate a
warning in the corresponding subsystem, and 5, 6, or 7 would indicate a
failure.

Grace and peace,

Jim
