It's specified as a fixed value in the docs provided by the vendor. In my 
understanding a value of 1 means the data is compliant to ISO/IEC 7816-15:2016 
which replaces PKCS#15. A value of 0 means the data is compliant to PKCS#15 
(or at least older editions of ISO/IEC 7816-15). But the content is 
effectively the same.

Kind regards
