I have a question with regard to the discussion in SPC4r04 
In clause 7.6.4 Extended INQUIRY Data VPD page, there are 3 bits
discussed 
*	GRD_CHK, 
*	APP_CHK and 
*	REF_CHK
They are defined as far as their meaning, but never discussed how they
are set. 
Is this part of the format process, or simply the capability of the
device firmware or design?
I got a response that said go look at any protected command (i.e.
read/write, etc.), however that does not answer the question.
Are these 3 bits somehow tied to the format type (type 1, 2, or 3)
