If I understand correctly you are saying it should be something like:
<inventory>
<entry file_id="" text_sha1="" ...>
	<meta_info></meta_info>
</entry>
</inventory>

Is that correct?
Does cElementTree distinguish between the:
<entry />
And
<entry></entry>
forms?

Does it automatically split an entry if it has child objects? That would
naturally be the easiest way, because the reader can just check for a
child object named "meta_info", or <executable>True</executable>

I would actually like to see bzr adopt what tla-mainline did. Which is
if your tree contains some "track-meta-info" indicator, and your
personal configuration agrees with it, it will keep track of
permissions/owner/etc.

Naturally, I would want to think about it for a while, to figure out
what would be a good schema.

Also, it is obvious that we probably want to always keep track of the
execute bit. But I was wondering if we want to always track all of the
meta-info, and just not use it. I'm thinking permissions are pretty safe
to always keep track of. I probably wouldn't want to track owner/group
unless explicitly requested.

Is that reasonable?
