What steps are required to add a new language to an XM Cloud headless SXA site?

To add a new language to an XM Cloud headless SXA site, the correct approach involves adding the language in the designated languages directory and then configuring the relevant content to ensure that everything is set up correctly for the new language.

Adding the language in the /sitecore/system/languages section allows you to define the necessary parameters for the language, such as its name and culture code. After this, it is critical to configure content to ensure that existing items can be translated or localized appropriately. This includes potentially creating corresponding language versions of site content to prevent any gaps in content availability for users in that language.

Simply adding a language without configuring content may result in a language being recognized by the system but not actually having any associated content, which can be a significant issue in terms of delivering a fully localized experience to users.

The steps mentioned do not provide a complete role for systematic implementation, as they either skip the configuration phase or focus on actions that may not be supported in all scenarios. Thus, the comprehensive method of adding the language and then ensuring that the content is configured to accommodate it is vital.
