Properties and types language versions
You could very well use translations as subpages, e.g. Propiedades y tipos since this would help if we were to use the Translate extension on that page. Like this it is fine too.
About the docinfo template. On the translated page you are basically the one for support while Markus is still the original author. For master revision you add the revision number of the latest revision of the page you translated, like in this example.
