  Initial commit of what I've built already for those who prefer code to minimalistic design docs.

  Trick to avoid hard-coding the class name of EventProducer in the source file.
  Feel free to revert if it's not ok.
........
  r616900 | jeremias | 2008-01-30 21:59:31 +0100 (Mi, 30 Jan 2008) | 1 line
  
  Generate event model XMLs in to the build directory: build/gensrc and build/test-gensrc (the latter is new and needs to be setup as source folder in your IDE!)
........
  r616907 | jeremias | 2008-01-30 22:12:59 +0100 (Mi, 30 Jan 2008) | 1 line
  
  Added an XMLResourceBundle that uses an XML file instead of a properties file to load the translations. The XML format is the same as for Cocoon's XMLResourceBundle.

........
  r617176 | jeremias | 2008-01-31 19:14:19 +0100 (Do, 31 Jan 2008) | 5 lines
  
  Renamed FopEvent to Event as suggested by Simon.
  EventProducerCollectorTask.java now reads the EventSeverity from a doclet tag.
  Added generation of EventProducer translations (including simple merging, no validation, yet)
  EventFormatter introduced (only basic functionality, yet).
  Added a simple EventListener implementation that uses EventFormatter to convert the events to human-readable, localized messages that are sent to the log via Commons Logging.
........
  r617362 | jeremias | 2008-02-01 08:18:07 +0100 (Fr, 01 Feb 2008) | 1 line

  Extracted formatting functionality into utility class AdvancedMessageFormat.java.
  AdvancedMessageFormat.java now supports conditional sub-groups (delimited by []).
........
  r618682 | jeremias | 2008-02-05 17:07:08 +0100 (Di, 05 Feb 2008) | 1 line
  
  Add support for special object formatters (where toString() isn't good enough). ATM, it's hard-coded but could later be hooked into dynamic discovery if we have multiple such formatters. The SAX Locator is the only example for now.
........
  r618686 | jeremias | 2008-02-05 17:12:56 +0100 (Di, 05 Feb 2008) | 3 lines
  
  Hooked most of FONode into the new event mechanism. The FOUserAgent provides a DefaultEventBroadcaster instance.
  If a producer method declares throwing an exception, the event is automatically marked FATAL and the dynamic proxy throws an exception right after notifying the listeners.
  The exceptions are created through the EventExceptionManager. It currently contains only one exception factory for ValidationException. If we need more such factories it's better to register them dynamically. Right now, they're hard-coded.

  r619313 | jeremias | 2008-02-07 10:14:15 +0100 (Do, 07 Feb 2008) | 1 line
  
  Make sure no events are now just silently swallowed because after upgrading a user doesn't know about the event system.

........
  r631268 | jeremias | 2008-02-26 17:08:11 +0100 (Di, 26 Feb 2008) | 1 line
  
  Deprecated two methods which are a problem for localization. Also helps finding additional spots to switch over to the event mechanism.

  Javadocs.
  Moved out event listener registration into a CompositeEventListener.
  Event broadcaster uses the events effective severity, not the initial value (for the case where listeners override the initial value).
  Set up a special EventBroadCaster in the FOUserAgent that filters events through a class (FOValidationEventListenerProxy) that adjusts the event severity for relaxed validation.
........
  r633858 | jeremias | 2008-03-05 15:32:07 +0100 (Mi, 05 Mrz 2008) | 2 lines
  
  Instead of always decentrally checking whether strict validation is enabled or not, this is now done in a special event listener. The event producer method caller simply indicates whether it can recover from the error condition and continue.
  Started switching to event production in table FOs.
........
  r634027 | jeremias | 2008-03-05 21:58:35 +0100 (Mi, 05 Mrz 2008) | 7 lines
  
  Moved AdvancedMessageFormat into its own package.
  AdvancedMessageFormat got the following added functionality:
  - Alternative conditional regions [ bla {field}] -> [ bla {field1}| even more bla {field2}]
  - Functions: functions get access to the parameters and they can produce an object that is then formatted ({#gatherContextInfo})
  - "if" and "equals" format moved to top-level classes and added by dynamic registration.
  EventFormatter now supports includes in the form {{includeName}} so you can include other entries from the resource bundle for better reuse.
  Some more events in table code.

  r634381 | jeremias | 2008-03-06 20:12:57 +0100 (Do, 06 Mrz 2008) | 2 lines
  
  Made the "invalidChild" event fully localizable by adding a "lookup" field for the optional rule to be displayed.
  And a few switches to the event system.

  Non-FO children were not properly run through validation by FOTreeBuilder.
  Unified the way that non-FO elements are validated. Some FOs were already fixed. I now fixed the rest, so foreign elements can occur everywhere.

  Generalized FOValidationEventListenerProxy into FOPEventListenerProxy, the main proxy for FOP's own event manipulation proxy. Done because of support for overflow="hidden" vs. overflow="error-if-overflow".
  Switched block-level layout managers to events.
  Some cleanup along the way.

  Moved the creation of the fallback LoggingEventListener to FOUserAgent so event before the startDocument() SAX event arrive in the log.
  Dynamic discovery of event models. Renderers and extensions can register renderer-specific event models.
  Switched the most important parts of the renderers to events (maybe not everything is converted).

  Plugged fonts package into the event subsystem. Note: I did not follow the same pattern as for the rest as the font package is to be considered FOP-external, so I just added a manual adapter for the FontEventListener. This demonstrates how an external library can be integrated with the event system.
  Missing warning for unknown formatting objects added. Warning is not issued by the ElementMappingRegistry anymore but by FOTreeBuilder which has access to more context information.

  r642997 | jeremias | 2008-03-31 16:10:08 +0200 (Mo, 31 Mrz 2008) | 1 line
