Requirement_scenario

One state of affairs, the Dependent, cannot occur without another state of affairs, the Requirement, also obtaining. This Requirement is construed to be under the control of some implicit force or actor. In an alternative construal, the Dependent state of affairs may be presented as depending on the presence of a Required_entity. Individual that profit from the occurrence of the Dependent state, Dependent_individuals, are backgrounded. The same goes for individuals (Required_individual) that are required to provide any Required_entity or to see to the occurrence of the Dependent state of affairs. The nexus between Requirement and Dependent can be qualified further in terms of the Degree of strength of the link between the two eventualities, the Place and Time where this nexus obtains, the Reason for its existence, or a specification of Condition when it applies.
