-- EIN (Employer Identification Number) filter. A first-class entity type for the
-- U.S. federal business tax ID, format NN-NNNNNNN (e.g. 12-3456789), the business
-- counterpart to SSN. It is distinct from SSN (different format and semantics), so
-- a policy can handle the two independently. The optional onlyValidPrefixes flag
-- (default FALSE) restricts matches to EINs whose two-digit prefix is one the IRS
-- issues, cutting false positives on format-valid but non-issued numbers; it is
-- set through the filter OPTIONS passthrough, like creditCard's
-- onlyValidCreditCardNumbers. New in schema 1.2.0. Compiles to ein.json.
