Meaning#

unitcategorylookup: 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 unitcategory.attack
enumeration unitcategory.build
enumeration unitcategory.defence
enumeration unitcategory.gascollector
enumeration unitcategory.guard
enumeration unitcategory.orecollector
enumeration unitcategory.police
enumeration unitcategory.repair
enumeration unitcategory.transport

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.
