In the context of Network management, Chomicki, Lobo and Naqvi have defined the specification language PDL (Policy Description Language) and later extended it by introducing monitors: constraints on the actions that the network manager cannot execute simultaneously.
We argue that PDL with monitors is an appealing language that can be applied to specification and implementation of intelligent systems beyond network management. To do so, we discuss two extensions of it. In the first extension monitors are defined as computing a maximum set of actions compatible with the constraints, rather than a maximal one. The inevitably higher computational complexity of this extension is assessed. In the second extension, negative events, a device already introduced by Chomicki et al., are treated as equivalent to regular events, thus allowing more intuitive results from monitor application.
