Possibly, I think the doxygen comment of OpenNI2Grabber is wrong.
Do you have any ideas for resolve this problem?

[UnaNancyOwen]

Other grabbers don't have nested namespace.
But, only OpenNI2Grabber have nested namespace. (I don't know this reason. why?)
I think that this is related to this issue.

• Other Grabber

namespace pcl
{
  /** \brief Other Grabber
   * \ingroup io
   */
  class PCL_EXPORTS OtherGrabber : public Grabber
  {
  };
}

• OpenNI2 Grabber

namespace pcl
{
  // insert more doxygen comments in here? or delete this namespace?
  namespace io
  {
    /** \brief OpenNI2 Grabber
     * \ingroup io
     */
    class PCL_EXPORTS OpenNI2Grabber : public Grabber
    {
    };
  }
}

See discussion about the io namespace in #888 and #975.
