Dev0153 through Dev0160 look like they were derived from an earlier edition of S-100 than Ed. 5.1, probably back before Part 17 was split off from Part 4a. For example, I can't find a statement about producer agency code or a producer code register in Part 4a of Ed. 5.1. This may have moved into Part 17 (beginning Edition 5.0.0, I think).
The larger implication is that all the "S-101 checks" need to be checked to verify the corresponding S-100 reference.
Some (all?) of the Part 4a checks (currently Dev0153 - Dev0160) were transferred from the S-101 list and should have their references updated to the appropriate clauses (if any) in S-100 5.2.0 Part 17.
