- In cases where a property in Swap Pim is defined as equivalent to another property in a different name·space, it is strongly recommended that you use the other property instead.
+ Two terms in the <code>airports:</code> name·space, <ptr target="airports:iata"/> and <ptr target="airports:icao"/>, are also defined, for use with <ptr target="contact:nearestAirport"/>.
