Some properties are supposed to represent integers. As an editor I want to be able to define which properties these are so I can easily find cases where the property is used in a wrong way via the existing constraint system.
Violation message shown to the user on violating statements: "Integer constraint: This "$property" statement should only take integer values."
Constraint statement on the property: "property constraint" -> "integer constraint"
Examples where this is likely to be used:
- number of children of a person
- number of participants in an event
