  24                  | SOR <bool>
  25                  | <bool>
  26      <bool>    ::= <bool> and <term>
  27                  | <bool> or <term>
  28                  | <term>
  29      <term>    ::= not <factor>
  30                  | <factor>
  31      <factor>  ::= <bool>
  32                  | <boolval>
  33                  | <depinst>
  34                  | <termval>
