title: Enterprise Library 5.0 - Adding custom tokens to a TextFormatter
body: <p>I have created a custom Exception that has data pertaining to our application.  I want to ensure this data gets logged when an exception is thrown and logged to the event log.</p>
  
  <p>I have tried creating a custom TextFormatter which is being called but am not sure how to access the current exception so I can add our custom information to the log entry.</p>
  
  <p>There is something I am not understanding and would appreciate any help around adding custom tokens (and data) to Enterprise Library 5.0 TextFormatters.</p>
  
  <p>Thanks,
  ...Marc</p>
