Currently it's just concatenating `message` and `complement`. https://github.com/vue-a11y/vue-announcer/blob/e19a2dfb2437fef0ea86c16ae8d08f9bfac6b7f5/src/index.js#L79 For i18n purposes, it would be nice to pass a function when installing the plugin that would allow to define how this works, something like: ```js (message) => { return this.$gettext('%{ message } has been loaded'); } ```
