I was deadset against it myself until Hans pointed out its virtues
(mainly, human readability).
It's not necessarily XML, though it may eventually end up as such. Right
now I just see it has a system of tags for specifying characteristics and
segmenting data.

If you're thinking in terms of having the original hardware around to
write the imagefile back to its original media (like I have), then getting
the data at a logical byte level is adequate. It depends on what your
eventual goal is for the image. Is it just to capture the data on the
medium so that it can be accessed in the future without regards to whether
the original hardware still exists? Or do you intend to be able to
reconstruct the physical medium at some point?
The spec should be able to handle either case.

Or it could specify what data it contains, and then you would use it as
appropriate.

And other media as well (paper, plastic, etc.) That's what we're tyring
to do here. Hopefully we don't end up with something as bloated as PDF
however :)
