Error in DITA Language Spec (all versions)

The DITA Version 1.1 Language Specification, and all
previous versions including 1.0.1, has an error in
the example for <keywords> on page 150 of the PDF.  

It shows:
  <prolog>
    <keywords>
      ...
    </keywords>
  </prolog>

instead of the correct:
  <prolog>
    <metadata>
      <keywords>
        ...
      </keywords>
    </metadata>
  </prolog>

as required by the content models (which are correct).

HTH!
