	<type>stimulus/dc</type>
	<name>DC</name>
	<definition>Property definitions to describe a DC stimulus meaning a constant stimulus e.g. a constant illumination, current etc.</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>Intensity</name>
	      <value>
			<type>string</type>
	      </value>
	      <definition>The stimulus intensity in absolute or relative terms.</definition>
      </property> 
      
      <property>
	      <name>IntensityOffset</name>
	      <value>
			<type>string</type>
	      </value>
	      <definition>The stimulus intensity given as the offset relative to another stimulus.</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 constitutes 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 explicitely express that several stimuli (that share the same OutputChannel) are jointly presented.</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

	      </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>
