Methodological lineage

The deontic-modality pattern list draws on the Mercatus
Center / George Mason University QuantGov project's RegData
methodology for counting US regulatory restrictions (must,
shall, may not, prohibited, required). QuantGov is Apache-2.0;
the actual pattern strings here are adapted independently for
German legal-text idioms.

The OBLIGATION / PROHIBITION / PERMISSION taxonomy follows
LegalRuleML (OASIS) and the broader deontic-logic tradition.
