Thanks for catching those errors.  I have posted a corrected proposal.
I had intended to add the tape diagnostic data log page (16h) to the list of
pages available to the ADC device server but hadn't put the updated table in
the proposal.  I have added it to r1 as well as corrected the typos you

1) The comment talks of the HRE bit.  I assume that is the TDDEC bit.
2) The TDDEC bit is called "tape diagnostic data encrypt created".  Why is
"encrypt" in here?  You descriptions and front material make no mention of
encryption.  I think you must have carried "encrypt" over from something
else.  Or maybe it is supposed to be entry instead of encrypt?
3) Log Page 16h is not available on an ADC device.  Do you plan to add this
page as an available page for ADC devices?  It looks like you do because you
use the phrase, "by this I_T nexus" which I am interpreting as this I_T_L
nexus.	Perhaps you really do mean this I_Tnexus and the L is intended to be
the SSC LUN.
