28   * An interface which defines the contract for context definition objects.
29   * <p>A context is a set of related krms entities. A context definition
30   * defines information about a context which can be loaded into the rules
31   * engine for evaluation.
32   *
33   * A context definition includes a list of agendas which are valid within the
34   * context.  Typically, during rule engine execution, one or more of these
35   * agendas is selected for execution based on a given set of selection criteria. All KRMS components
36   * (agendas, rules, actions, terms, etc.) must be of the same context to
37   * work together. It is up to the client implementor to choose how broadly or
38   * finely grained the scope of the context is to be.
