[SMIL21] Example with calcMode="discrete" and keyTimes

Hi.

There is an example[1] in SMIL 2.1 (which is also in SMIL Animation)
that uses calcMode="discrete", a values and a keyTimes attribute, but
the number of values and keyTimes do not match.  The example is:

  Discrete animation can be used with keyTimes, as in the following
  example:

    <animateColor attributeName="color" dur="10s" calcMode="discrete"
                  values="green; yellow; red" keyTimes="0.0; 0.8;" />

  This example also shows how keyTimes values can interact with an
  indefinite duration. The value of the "color" attribute will be set to
  green for 5 seconds, and then to yellow for 5 seconds, and then will
  remain red for the remainder of the document, since the (unspecified)
  duration defaults to "indefinite".

Yet in the prose for the keyTimes attribute it says:

  If a list of keyTimes is specified, there must be exactly as many
  values in the keyTimes list as in the values list.

Is the example incorrect or can key times indeed be omitted?

Thanks,

Cameron
