I would add that beside bumping the version, the matching changes or
additions in behavior must be described.
With regards,
David.

Subject: Minor changes to sync MMC-6 with Mt. Fuji 7
Bill,
With MMC-6 under development, and Mt. Fuji 7 released, I wanted to note the
following issues:
1.)  MMC-6 5.3.35 defines Version 0 of the HD DVD Read (0050h) Feature
Descriptor.  Mt. Fuji 7 defines Version 2.
2.)  MMC-6 5.3.36 defines Version 0 of the HD DVD Write (0051h) Feature
Descriptor.  Mt. Fuji 7 defines Version 2.
Regarding #1 and #2 above, with HD-DVD no longer being developed, should all
HD-DVD references be removed and replaced with an "Obsolete" note?  This
would resolve #1 and #2 above as you can delete the entire sections and
simply state that they're obsolete (as well as other HD-DVD sections in the
specification).
3.)  MMC-6 5.3.45 defines Version 4 of the Real Time Streaming (0107h)
Feature Descriptor.  Mt. Fuji 7 defines Version 5.
4.)  MMC-6 5.3.51 defines Version 0 of the AACS (010Dh) Feature Descriptor.
Mt. Fuji 7 defines Version 1.
5.)  MMC-6 5.3.32 defines Version 0 of the BD Read (0040h) Feature
Descriptor.  However, Version 1 of this descriptor is in use by shipping
drives today.  Version 1 adds the "BCA Read" flag.  Can this be added for
the next MMC-6 update?
Unrelated to the above, if there is any ODD vendor that supports the new
MMC-6 OSSC Feature Descriptor (0142h), and if you would like to work
together to add support for this feature, please contact me privately.
