A break statement is not required following the default case because it would not affect the control flow.
Exceptions
MSC17-C-EX1: The last label in a switch statement requires no final break. It will conventionally be the default label.
MSC17-C-EX2: When control flow is intended to cross statement labels, it is permissible to omit the break statement. In these instances, the unusual control flow must be explicitly documented.
