Looking for definition for the SMART attribute 174 / AEh used in 710 Series

[idata]

My 710 Series drive has a SMART attribute with ID 174 (or AEh) :

174 Unknown_Attribute 0x0032 100 100 000 Old_age Always - 4

This attribute is not defined in the Intel specification document:

If anyone knows anything about this attribute please speak up.

Thanks.
