Since Part B is not mandatory, why is it part of the convention and not the subject of an international labour recommendation?

Part A and Part B of the Code are interrelated. The provisions of Part B, called Guidelines, while not mandatory, are helpful and sometimes essential for a proper understanding of the Regulations and the mandatory Standards in Part A. In some cases, the mandatory Standards in Part A are so generally worded it may be difficult to implement them without the guidance in the corresponding provisions of Part B.
