Types:
    Nativ: null, string, number, JSON
    Fqid: Strukturierter string
    HTML: string mit HTML Inhalt
    <T>[]: Array von Typ T
    <modellname>: number (ID) zu dem Modell
    float: string mit iso-gemäßer Formatierung eines floats
    decimal(X): Decimal values represented as a string with X decimal places
    datetime: Datetime as a unix timestamp
    // Why a number? This enables queries in the DB. And we do not
    // need more precision than 1 second.

Note to structured fields: Fields with `some_field_<some_variable>` do have
values for `<some_variable>` that fits into the format of a field. E.g.
`amendment_paragraph_3`. Note that it might be possible that no kind of
this field exists in a model.
