This definition is used in the extension.xml file to specify the properties of an extension.

There are several properties which can influence availability and load order. These tags take priority in this order: ruleset, exclusiongroup, dependency, loadorder.

The ruleset property determines whether the extension is shown for a given campaign based on the ruleset used. If the minrelease and/or maxrelease subtags are specified, and the ruleset version does not match, then the extension will be shown as broken on the launcher screen, and not be selectable.

If the exclusion group property is defined, only the first extension within a given exclusion group will be loaded. All other extensions with the same exclusion group property will be skipped.

If the dependency property is defined, the extension on which the current extension is dependent will always be loaded first. If the extension on which the current extension is dependent is not available and selected, then this extension will not be loaded.

The loading order for extensions is defined by starting with the largest loadorder property for an extension down to the lowest loadorder property. If two extensions have the same load order value, then they are loaded in alphabetical order. If no load order value is defined, then zero is assumed.
