>&#13;   Returns the old value for the changed property.
   This can be used by a Data Access Service when 
   writing updates to a data source.
   The DAS uses the old value to detect conflicts by comparing 
   it with the current value in the data source.
   If they do not match, then the data source has been updated 
   since the data object was originally populated, and therefore
   writing any new updates risks compromising the integrity of the data.
