(documentationinitiallyContainsPartEnglishLanguage "Every instance of the second argument initially contains an instance of the first argument, even though it might lose that part later in its lifetime. Every normal human starts life with an appendix for example. While the whole must initially contain such a part, this does not say that each part necessarily initially exists as part of such a whole. This is a class-level relation roughly corresponding to part.")
