Plugins can add new ContentServices by declaring them in their XML file as follows :
<!-- Contents Service --> <content-services> ... <content-service> <content-service-id>myContentService</content-service-id> <content-service-class>fr.paris.lutece.plugins.myplugin.service.MyContentService</content-service-class> </content-service> ... </content-services>
