-------- DESCRIPTION  
---------------------------------------------------------

Feed Element Mapper is an add-on module for FeedAPI that maps elements on a
feed item such as tags, or the author name, to taxonomy or CCK fields. These
mappings are configurable by a point and click interface. When configuring
the mapping, some values coming from external feeds are not sanitized before
they are displayed, leading to a Cross Site Scripting (XSS [1])
