the spec again, I realized that, if "always" is stronger than any 
numeric value, it is of infinite strength.  In fact, the spec, in 4.8,
has: the value| "always"| being stronger than *all* numeric values (my

Given that, it is reasonable 
to conclude that an "always" keep cannot be broken under any 
cicumstances, which is what "always", independently of the particulars 
of the spec, always means.
