It has always been my understanding that the position of EOP is allowed to vary
|from mount to mount and even from writing to reading.  (Read limits being opened
up to always allow tape interchange reading on a drive with worst possible
variations in EOP positioning).  It isn't clear from reading the SSC document
that this variation is allowed.  Could we get a clarification on this?  I have
an application where it is assumed that EOP will be asserted on the exact same
logical block read as it was when written.
