/**
 * Build the (client-side) validation schema for the address NL data.
 *
 * Because this is a composite, the validation logic is a bit different from what we're
 * used to.
 *
 * A required addressNL component means that:
 *
 * - the postcode field is required
 * - the house number field is required
 *
 * since these are the minimal atoms that allow you to resolve an address.
 *
 * House letter and house number addition are always optional, because not every address
 * has those.
 *
 * When address derivation is enabled, the street name and city fields become visible
 * and they're either auto populated, or due to an error manually filled in by the user.
 * This makes the fields mandatory (!).
 *
 * Furthermore (this applies to optional address NL fields), you must either provide
 * both the postcode and houser number, or none at all, as partial data does not make
 * sense. Here too, if address derivation is enabled, filling out one field requires
 * that city and street name are populated too.
