Protect Stop Date question

From Section 3.26 Protect Stop Date in KMIP 1.4 spec, and the same wording in Section 4.41 KMIP 2.0 draft

The Protect Stop Date attribute is the date and time after which a Managed Symmetric Key Object SHALL NOT be used for applying 

cryptographic protection (e.g., encryption or wrapping), depending on the value of its Cryptographic Usage Mask attribute. This value 

MAY be equal to or earlier than, but SHALL NOT be later than the Deactivation Date. Once the Protect Stop Date has occurred, then this 

attribute SHALL NOT be changed or deleted before the object is destroyed

I added the emphasis.   Does this mean that the Protect Stop Date attribute only applies to Symmetric Keys?

I ask this question because published test cases CS-AC-M-8-13, -14, -20 all define this attribute for a Key Pair Managed object.

Do I have an old version of these test cases?
