/**
* Provides access to the localized messages for the OpenCms workplace.
*
* The workplace messages are collected from the workplace resource bundles of all installed modules,
* plus all the OpenCms core packages.
*
* To be recognized as a workplace module resource bundle,
* the workplace property file must follow the naming convention ${module_package_name}.workplace${locale}.properties,
* or ${module_package_name}.messages${locale}.properties
* for example like com.mycompany.module.workplace_en.properties or
* com.mycompany.module.messages_en.properties.
*
* Workplace messages are cached for faster lookup. If a localized key is contained in more then one module,
* it will be used only from the module where it was first found in. The module order is undefined. It is therefore
* recommended to ensure the uniqueness of all module keys by placing a special prefix in front of all keys of a module.
*
* @since 6.0.0
