Multilingual descriptions are placed between [lang=xx] and [/lang] tags, where xx is the language code (for example en, es, fr). There are also 2 special languages : [lang=default] and [lang=all]

The default description will be used if the description is not available in the connected user selected language. If [lang=default] does not exists, anything outside the [lang] tags will be considered as the default description.

Special language all: anything inside [lang=all] will be included in the description, whatever the connected user defined language is. This is mainly useful to include HTML/JavaScript code inside a description.
