As a concrete example, the following definitions would need to be created for a Local Code System that groups codes related to medicinal products:
tradeName

Cardinality: 1..*
Description: Trade name of the medicinal product.
Validation expression: _this.value == _this.value.toUpperCase()
Validation message: Trade name '%s' needs to be all uppercase.
isVaccine
Type: Boolean
Cardinality: 1..1
numberOfBlisters
Type: Integer
Cardinality: 0..1
Default value: 6
Description: The number of blisters in the product.
Validation expression: _this.value > 0
Validation message: Number of blisters '%s' needs to be a positive number.
URI property types do not support validation expressions. In case of trying to enter something in the Validation expression field of a URI-type property, an error message will be present in the editor.
Certain property names are reserved and cannot be used as names for additional properties. The following property names fall under the reserved category: Code, Term, Alternative Terms, Is active, and Parent Concept Code. Entering one of the reserved property names will trigger an error message in the editor.
The icon warns the user that if the value of cardinality is reduced, properties may be deleted from that terminology. Hovering over the icon reveals the warning message.
