+  <p>A string provided by a script (e.g. the argument to <code title="dom-alert"><a href="#dom-alert">window.alert()</a></code>) is expected to be treated
+  as an independent set of one or more bidirectional algorithm
+  paragraphs when displayed, as defined by the bidirectional
+  algorithm, including, for instance, supporting the
+  paragraph-breaking behaviour of U+000A LINE FEED (LF) characters. <a href="#refsBIDI">[BIDI]</a></p>

+    then the bidirectional algorithm will determine that the direction
+    of the paragraph is right-to-left, and so the output will be
