The test says:

   * Check that the Raw._*_NDX indexes are sequential
   and followed by the FIXED_LENGTH value.
   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

though the code does not verify that FIXED_LENGTH is the final value.  I 
don't know that it's all that important to do, but I thought I'd point 
it out.

Thanks,
