The NIEM CUI schema currently supports use of 3-character GENC codes only. It does not support use of digraphs, numeric country codes, or subdivision codes. However, per CUI program office: support for additional REL TO and DISPLAY ONLY options (see IC-ISM tetragraphs and NATO pattern) should be added.
Per CUI meeting 9Oct20: NIEM's CUI RELTO option will include a substitutable property with one substitutable element for GENC country code trigraphs for use with CUI RELTO and DISPLAY ONLY limited dissemination controls.
The U.S. Government agencies are required to use the GENC profile of ISO 3166-1 and not use pure ISO 3166-1.
However, NIEM imports GENC digraphs, trigraphs, and numeric country codes, and subdivision codes.
