Different hippo documents that are translations of the same page can be linked as multi-lingual documents by adding the hippotranslation:translated mixin to these documents.

This mixin adds the properties hippotranslation:locale and hippotranslation:id to the corresponding nodes.

When the value of the hippotranslation:id property is equal for two different pages that have different values for the hippotranslation:locale property, they are recognized as translations of each other.

The same technique can be applied to link two different folders as translated folders.
