Sample: a representative value of the parameter's type that is truthy (a non-empty
string or array, a non-zero number, true, a date). The caller picks the actual value.
Absent: no value; the parameter is left out, so it is falsy.
Literal: exactly this value, to satisfy a comparison such as mode == 'big'.
