\$rss->as_rss_$f()
WARNING: this function is not an API function and should not be called directly. It is kept as is for backwards compatibility with legacy code. Use the following code instead:
\$rss->{output} = "$rss";
my \$text = \$rss->as_string();
This function renders the data in the object as an RSS version $rss feed, and returns the resultant XML as text.
