Added <dc:language> to RSS2 feed

After a short visit to the WordPress Developer’s Wiki I have hacked a (kind of proof-of-concept) dc:language extension to the RSS2 feed. I am really unsure if this can be handled using plugins or actions?? For now only the wp-rss2.php has been modified and I added a file called [dcmi.php][2], just download, put in the WordPress root and rename them to *.php… After adding a custom field named dc:language to your post, the RSS2 feed should show up the new language, or the default falue of “en”. The language for the RSS2 Channel defaults to “en” (which is hardcoded at wp-rss2.php).
