 ## Operations related to territories
 
 A territory is identified by a code (an ISO 3166 code such as “NLD” or "US-DC"), with some
 possible aliases (example "US" = "USA"), and a unique number, from 0 for "VAT" (Vatican),
-to 532 for "AAA" (International), defined as Territory_Range.
+to 532 for "AAA" (International), defined as `Territory_Range`.
 
 Large territories (MX, IN, AU, BR, US, CA, RU and CN) are decomposed into subdivisions.
