+AutoFormat.RemoveEmpty
+TYPE: bool
+VERSION: 3.2.0
+DEFAULT: false
+--DESCRIPTION--
+<p>
+  When enabled, HTML Purifier will attempt to remove empty elements that
+  contribute no semantic information to the document. The following types
+  of nodes will be removed:
+</p>
+<ul><li>
+    Tags with no attributes and no content, and that are not empty
+    elements (remove <code>&lt;a&gt;&lt;/a&gt;</code> but not
+    <code>&lt;br /&gt;</code>), and
+  </li>
+  <li>
+    Tags with no content, except for:<ul>
+      <li>The <code>colgroup</code> element, or</li>
+      <li>
+        Elements with the <code>id</code> or <code>name</code> attribute,
+        when those attributes are permitted on those elements.
+      </li>
+    </ul></li>
+</ul>
+<p>
+  Please be very careful when using this functionality; while it may not
+  seem that empty elements contain useful information, they can alter the
+  layout of a document given appropriate styling. This directive is most
+  useful when you are processing machine-generated HTML, please avoid using
+  it on regular user HTML.
+</p>
+<p>
+  Elements that contain only whitespace will be treated as empty. Non-breaking
+  spaces, however, do not count as whitespace.
+</p>
+<p>
+  This algorithm is not perfect; you may still notice some empty tags,
+  particularly if a node had elements, but those elements were later removed
+  because they were not permitted in that context, or tags that, after
+  being auto-closed by another tag, where empty. This is for safety reasons
+  to prevent clever code from breaking validation. The general rule of thumb:
+  if a tag looked empty on the way end, it will get removed; if HTML Purifier
+  made it empty, it will stay.
