I did some research in this some time ago, as I recall you need a Trademark file which works sort of in the same way as the bootblocks works on a diskette.
You also need to use burning software on the Amiga (afaik atleast) to be able to "use" this trademark file when creating the CD but I think you can burn the iso with any program you want when it's built.
Uhm, and I think the trademark files can be found on some developer cd, never got as far as getting my hands on it.
But this is all from what memory so some things might be completely wrong :/ might help a little atleast
