This property generalises relationships like whole-part, sequence, prerequisite or inspired by between instances of E29 Design
or Procedure. Any instance of E29 Design or Procedure may be associated with other designs or procedures. The property is considered to be
symmetrical unless otherwise indicated by P69.1 has type. The P69.1 has type property of P69 has association with allows the nature of the
association to be specified reading from domain to range; examples of types of association between instances of E29 Design or Procedure
include: has part, follows, requires, etc. The property can typically be used to model the decomposition of the description of a complete
workflow into a series of separate procedures.
