    <definition>Property definitions to describe Gabor stimuli.</definition>

    <property>
      <name>Modality</name>
      <value>
        <type>string</type>
      </value>
      <definition>The stimulus modality like acoustic, haptic, light etc.</definition>
    </property>

    <property>
      <name>Duration</name>
      <value>
        <type>float</type>
        <unit>s</unit>
      </value>
      <definition>The duration of the stimulus in seconds.</definition>
    </property>

    <property>
      <name>TemporalOffset</name>
      <value>
        <type>float</type>
        <unit>s</unit>
      </value>
      <definition>The temporal offset (with respect to the begin of the recorded trial) with which this stimulus was
        presented.
      </definition>
    </property>

    <property>
      <name>Function</name>
      <value>
        <type>string</type>
      </value>
      <definition>The function of the described stimulus. E.g. if the white noise constituted the carrier.</definition>
    </property>

    <property>
      <name>OutputChannel</name>
      <value>
        <type>string</type>
      </value>
      <definition>The physical output device (e.g. an analog output channel, a monitor screen, the same loudspeaker,
        etc.). This information can be used to explicitly express that several stimuli (that share the same
        OutputChannel) are jointly presented.
      </definition>
    </property>

    <property>
      <name>Dimension</name>
      <value>
        <type>float</type>
      </value>
      <definition>The dimensionality of the gabor.</definition>
    </property>

    <property>
      <name>Position</name>
      <value>
        <type>2-tuple</type>
      </value>
      <definition>The position of the stimulus on e.g the screen. Specified as a 2-tuple (x;y). By default this position
        refers to the top-left corner of the object or its bounding box.
      </definition>
    </property>

    <property>
      <name>PositionReference</name>
      <value>top-left
        <type>string</type>
      </value>
      <value>center
        <type>string</type>
      </value>
      <value>bottom-right
        <type>string</type>
      </value>
      <definition>By default stimulus positions are specified by the coordinates of the top-left corner (or of the
        bounding box). Use this property for other definitions.
      </definition>
    </property>

    <property>
      <name>SpatialExtent</name>
      <value>
        <type>2-tuple</type>
      </value>
      <definition>The spatial extend of the presented stimulus (width;height) e.g. (1024;768).</definition>
    </property>
