/**
 * The TextUsernameAdapter replaces text fragments with the tag
 * ... The values of the item will be replaced with the
 * display name from the corresponding user profile display name.
 * 
 * Example:
 * 

 * {@code
 *    Workitem updated by: namcurrenteditor.
 * }
 * 

 * This will replace the namcurrenteditor with the corrsponding profile full
 * username. If the username item value is a multiValue object the single values
 * can be spearated by a separator
 * 

 * Example:
 * 
 * {@code 
 * Team List: txtTeam
 * }
