This property associates a particular instance of E7 Activity which realized an Activity Plan in a way regarded as valid by the actors intending it. (Should we require that a realization falls within the period of intending it?)
This property associates the beginning of an instance of EXX Intention to Apply with an explicit activity initiating it. Often, the initiation of intention to apply is implicit in the creation of the activity plan.
This property defines the kind of objects used in an E7 Activity, when the specific instance is either unknown or not of interest, such as use of "a hammer".
