Easy: the definition follows from the intended usage:

 ISO file when copied to the media sector-by-2048b-sector should
 produce the identical disk.  (Which implies that some disks cannot be
 mapped to ISO files - they may contain errors in 2376-byte (sp?)
 sectors correctable during translation to 2048b-sectors, etc.)

All bytes matter during copying.  So ISO files produced by reading a
disk must be identical.

Hope this helps,
Ilya

P.S.  I use readcd to produce ISO files, cdrecord (or "flavors", like
      dvddao) to burn them.
