<p id="res-2634"><b>Proposed resolution:</b></p>

  <p>
    <i>Change 6 [fs.filesystem.synopsis]:</i>
  </p>
  <blockquote>
    <pre>
      enum class directory_options<ins>;</ins>
      <del>{</del>
      <del>none,</del>

  </blockquote>
  <p>
    <i>Add the following sub-section:</i>
  </p>
  <blockquote>

    <h3>
      10.4  Enum class <code>directory_options</code> [<a name="enum.directory_options">enum.directory_options</a>]

    <p>
      The <code>enum class</code> type <code>directory_options</code>
      is a bitmask type (C++11 &sect;17.5.2.1.3) that specifies bitmask constants used to identify
      directory traversal options.
