    The majority of the XAML that defines the ControlTemplate for the Bookmark Control was obtained
    by using Microsoft Blend. See the blog post entitled: 'Use control templates to customize the

  <!-- 
  Add a TimeSlider to control the display of what geographic features are displayed in the Map Control
  based upon a specified TimeExtent. In the case of this sample code, when the specific Graphic elements 
  have a TimeExtent that falls within the Map.TimeExtent will they be displayed based upon the MyTimeSlider 
  settings.
  
  Tip: It is the x:Name Attribute that allows you to access the TimeSlider Control in the code-behind file. 
    
  The Loop Attribute of True allows continuous playing of the TimeSlider once it initialized in the code-behind.
      
  The PlaySpeed Attribute follows the format of "hh:mm:ss" where, hh = hours (0 to 24), mm = minutes (0 to 60),
  and ss = seconds (0 to 60). In this example the PlaySpeed increments the time intervals every tenth of a second
  (i.e. 0.1).
      
  The TimeMode Attribute of CumulativeFromStart means there is a fixed start date/time (2000/08/04 00:00:00 UTC
  in this example) that does not change and an end date/time that adjusts as the specified Interval (one day 
  in this example which is set in the code-behind) increases. As the 'thumb' of the TimeSlider control moves
  to the right along the slider track the TimeExtent Interval of the TimeSlider increases.
      
  The MinimumValue Attribute specifies the starting date/time of the TimeSlider track.
      
  The MaximumValue Attribute specifies the ending date/time of the TimeSlider track.
    
  The Value Attribute specifies the date/time location of the thumb along the TimeSlider track. The thumb can 
  have a start date/time and end date/time set for a TimeExtent which will display a window of time as the
  thumb moves along the TimeSlider track but this is best for TimeMode Attribute of 'TimeExtent'. Since
  this example is showing a TimeMode of 'CumulativeFromStart' it is best to have the thumb just use a single
  date/time specified for the Value set to the same date/time as the MinimumValue.
    
  The last thing needed to enable the full capabilities of a TimeSlider (i.e. having the PlayPause, Next, 
  and Previous buttons) is to set the Intervals Property. In Silverlight, this can only be done in code-behind to 
  construct the Collection Type of IEnumerable(Of Date). Without the TimeSlider.Intervals being set the user 
  has to manually move the thumb across the TimeSlider track to change the Map.TimeExtent and thereby see what 
  Graphics can be displayed for that date/time window.
