So, I've had a look, and as Ben has pointed out, the Compositions are
indeed binary xml. Their structure is not entirely straight forward,
but it would seem simple enough to write some custom code to add
elements to an existing template composition. This should suffice for
my purposes (basically, adding more spheres/cylinders inside a
trackball patch), but it would still be nice to have either an API or
at the very least some documentation so that compositions could be
created from scratch. I have submitted a feature request (rdar://
4971181) summarizing these requirements. Here's hoping that Quartz
Composer just keeps getting better and better!
Cheers!

Hi,
from my guess Quartz Compositions are just binary xml files. You can
open them with the Property List Editor. I haven't tried yet to
create my own .qtz this way, but if you do, please post your results.

Hi,
I tried a search through the mailing list, the dev docs, and on-
line, but couldn't find a definitive yes or no, so I thought I'd
pose the question to this list:
Is it possible to create a Quartz Composition in code?
I already understand how to publish ports and control a composition
in code, but this is not exactly what I'm looking for (though, I
suppose with a creative enough composition I could potentially
achieve the same results). Basically, I'm looking to use QC as a
shortcut for drawing some simple shapes in space and moving them
around. The issue is that I'd like to determine how many shapes,
their sizes, and their positions at runtime. In other words, I'd
like to not have to code the raw GL! ;-)
So, does anyone know if this is possible? Thanks in advance for any
help and/or advice!
