<p>These elements are less common, but are useful for niche applications and may
be present in any <abbr title="Rich Site Summary">RSS</abbr> feed.</p>
<p>An <abbr title="Rich Site Summary">RSS</abbr> feed can specify a small image which some
aggregators display as a logo.</p>

<p>Feeds and entries can be assigned to multiple categories, and in some versions
of <abbr title="Rich Site Summary">RSS</abbr>, categories can be associated with a
“domain”. Both are free-form strings. For historical reasons,
<strong class="program">Universal Feed Parser</strong> makes multiple categories available as a list
of tuples, rather than a list of dictionaries.</p>

<p>Each item in an <abbr title="Rich Site Summary">RSS</abbr> feed can have an “enclosure”, a
delightful misnomer that is simply a link to an external file (usually a music
or video file, but any type of file can be “enclosed”). Once rare, this
element has recently gained popularity due to the rise of
<a class="reference external" href="http://en.wikipedia.org/wiki/Podcasting">podcasting</a>. Some clients (such
as Apple’s <strong class="program">iTunes</strong>) may automatically download enclosures; others
(such as the web-based Bloglines) may simply render each enclosure as a link.</p>
<p>The <abbr title="Rich Site Summary">RSS</abbr> specification states that there can be at
most one enclosure per item. However, Atom entries may contain more than one
enclosure per entry, so <strong class="program">Universal Feed Parser</strong> captures all of them
and makes them available as a list.</p>
