I want to add a <enclosure> tag to the syndication extension. How can I shoot attached documents?
<enclosure url="http://example.com/file.mp3" length="123456789" type="audio/mpeg">
<item>
<title><![CDATA[{!! $entry['title'] !!}]]></title>
<description><![CDATA[{!! $entry['description'] !!}]]></description>
<content:encoded><![CDATA[{!! $entry['content'] !!}]]></content:encoded>
<guid>{{ $entry['permalink'] }}</guid>
<author><name>{{ $entry['author'] }}</name></author>
<pubDate>{{ $entry['pubdate']->format(DateTime::RSS) }}</pubDate>
</item>
