//! Liechtenstein VAT. Uses the Swiss UID system verbatim.
//!
//! Liechtenstein companies register under the Swiss UID scheme (CHE prefix,
//! same weights and check-digit algorithm). The only difference from `ch-vat`
//! is the `detected` label returned in a Valid verdict.
//!
//! Source: Swiss UID system covers FL (Fürstentum Liechtenstein) companies.
//! python-stdnum li.uid delegates to ch.uid.
