Dear Thomas,


I am sorry for the late reply.

Some proposals.

1. Specify the volume ID, which can be considered to be the name of the
image.

2. Other burning applications use the volume ID to set the volume name.

Maybe indent both entries.

I think, an article is missing. »as the name«

If that is a metaphor(?) for Microsoft Windows, note that on GNU/Linux
udisks does the same.

Please note how ID is spelled differently in the document. Maybe it
could be made consistent too.

As always thank you very much for the detailed explanation.

If the manual should stay as is, this is fine too. From my side, the
report can be closed nevertheless.


Thanks,

Paul
