- [I've created my first parser using RIS API, daily updated. Failed because I tried to do too much automatically (e.g. recognizing headers](https://gitlab.com/PhilippHofer/law)
- I don't want to restrict myself with a [parser combinators](docs.rs/nom) but code it myself using *recursive descent* parser.
- Be strict in what I process. Fail if anything unexpected happens. The user should handle this case. It's fine if one decides to ignore the new/unexpected field, but it should be done deliberately.
- [x] Parse risdok using own *RD parser*, again strict: fail if anything not expected happens, not sure (yet) if I want to operate on strings, or first parse using off-the-shelve XML reader (prob. 2nd option)
