+--DESCRIPTION--

+  Given that an element has no contents, it will be removed by default, unless
+  this predicate dictates otherwise.  The predicate can either be an associative
+  map from tag name to list of attributes that must be present for the element
+  to be considered preserved: thus, the default always preserves <code>colgroup</code>,
+  <code>th</code> and <code>td</code>, and also <code>iframe</code> if it
