Except that ISO images may have boot sectors/images conforming to the El
Torito bootable CD specification, metadata (such as the name of the
copyright holder, or the name of the authoring program), the directory
structure in multiple formats for various operating systems (8.3,
Joliet, Rock Ridge), versioning - and possibly even multiple sessions
(I'm not sure about this last one.) That information isn't extracted in
its entirety when you use WinRAR, so if you reauthor the CD after such
extraction it will no longer be identical to the original CD (or to an
ISO image of that original CD.)
