The established pattern is that we print -1 when its unset and "?" when
its totalling missing. So, how could this be invalid? It should be set
or not. That is unless its totally missing just like when we do not run
with selinux enabled and a context just doesn't exist.

Ok, so in this case it is clearly unset, so should be -1, which will be a
20-digit number when represented as an unsigned long long int.

Thank you for that clarification Steve.

It is literally a  -1.  ( 2 characters)
