There is very little documentation currently on how third-party settings work.

  • ThirdPartySettingsInterface has only this high-level documentation:

    Interface for configuration entities to store third party information.

    A third party is a module that needs to store tightly coupled information to the configuration entity. For example, a module alters the node type form can use this to store its configuration so that it will be deployed with the node type.

  • ConfigDependencyManager has the most thorough documentation on dependency management, but only mentions third-party settings in passing.
  • The config dependency handbook page is not complete and does not mention third-party settings at all.
  • The config schema handbook page has one example for third-party settings.
