Well, I'm, again 100% consistent in favoring ID over Id, but we have a lot of the latter and less of the former, so if you want to leave it alone, that's fine. Particularly since the schemas mostly have id or Id now, and it would be awkward to have those inconsistent.

As far as having a rule about it, I would say it's rare enough that we can just document particular choices.
