source: https://developer.mastercard.com/mastercard-send-person-to-person/documentation/field-uris-codes/gov-id-uris/index.md

The `government_id_uri` field can contain an array of data strings, which each identify a Government ID number for a Sender or Recipient.

Construct each data string according to the following properties and values. Start with `schema:id-number` and then append each subsequent `property=value` couplet using a semi-colon (;) separator. Example:

    dln:NHL12506717;expiration-date=2022-01-02;issue-date=2017-01-11;issuing-country=USA;issuing-place=New Hampshire
