Pick a DC citation ID format

[konklone]

This isn't a technical ask, but something it'd probably help to just get out of the way. What should we use as an ID format for citing sections of the DC Code?

As I describe in unitedstates/uscode#3, the US Congress uses usc/[title]/[section] in their official bill XML, so I followed suit for the citation IDs I added to the JSON "spine" that @tauberer updated the uscode repo to produce.

Would dc/[title]/[section] work for DC? So for example: dc/5/201 for § 5-201. For § 24-221.01c, it would be dc/24/221.01a. (§ 24-221.01a is a full-blooded section, not a subsection, and is a peer with § 24-221 and § 24-271.) For a subsection like § 24-221.01a(a), the cite would be dc/24/221.01a/a.

Uses: I'm going to add DC Code support to unitedstates/citation, using the good work that @waldoj did in #4. I'd also suggest a citation field as useful in the general purpose JSON this repo produces.

I don't know anything helpful except that it should have an extra level like dc/code/... since DC has a CFR equivalent as well.
