Meaning#

roompopulationtypeexprlookup: X4 attribute schema type: base types, constraints and value alternatives.

An XSD type constrains XML, rather than declaring a Lua return or the payload type of event.param. A valid schema value does not prove a successful game effect.

Schema structure#

libraries/common.xsd

Property Value
Construction union
Union members expression

Additional inline union branch:

Property Value
Construction restriction
Base type xs:string
Constraint Value
enumeration roompopulationtype.build
enumeration roompopulationtype.trade
enumeration roompopulationtype.drones
enumeration roompopulationtype.ships
enumeration roompopulationtype.repair
enumeration roompopulationtype.ammo
enumeration roompopulationtype.bar
enumeration roompopulationtype.administrative

restriction narrows a base type; union accepts one of its branches; list describes whitespace-separated items. Enumeration values in one restriction are alternatives. Pattern syntax is XML Schema regex, not Lua patterns or JavaScript RegExp. Constraints inherited from the base type still apply.
