Language Switch
Frontend language switch for multilingual sites
Description
This utility adds a language switch for all languages of the site (when using multilanguage the right way).
It takes its information from the navigation and fl-languages datasources.
Parameters are the most difficult part to implement as they come in one language only. It is therefore necessary to look up a parameter's translation in a datasource. For example: If your page is products and the parameter is $prodctgroup, you will need a datasource that lists all product groups in all languages. The xml shows an example. For sites with many parameters on different pages it might be useful to apply a template, placed on each page, from within the utility.
