The following is a XML definition I did some 3+ years ago
during a discusion, here on classiccomp (back when there
was one list *G*), as an example what a XML storage good
for everything from punch card to CD could be.
This example shows two CCDD structures, one showing an
IBMish tape, the other a disk for a popular 8 Bit micro.
(Back then nobody came up with the systems name :).
Someone asked recently how to handle multiple XML within
one file ... well, that's exactly the way it works :)
