The "Extended Approach" was chosen. Here's the current status:

DONE

Event interfaces and default implementations

DONE

Event model using QDox: detection of EventProducer interfaces, model generation and model parsing

DONE

XML-based ResourceBundle implementation

DONE

Generation and merging of the main English translation file for all event message templates (through an Ant task)

DONE

Message formatter with variable access (instead of parameter indices like in java.text)

DONE

Basic l10n for events so the events can be converted to human-readable messages, for example using the LoggingEventListener

DONE

Automatic throwing of exceptions for events marked FATAL

mostly DONE

Hooking the event system into FOP

Validation of the translation templates (verify that only available parameters are used, to avoid mistakes)

DONE

FONode.invalidChildError's ruleViolated parameter is a problem for l10n

Find out if we need some kind of event categorization. Right now, we only have an event ID but that is probably too fine-grained for most users. Instead of a (potentially hierarchical) categorization, we could also use tags: an "graphic not found" event would have the tags "missing-resource" and "graphic", so the user can either react on "misssing-resource" or all events involving embedded graphics.

Determine approach to integrate additional libraries with their own feedback mechanism or user agents. Batik has a user agent which allows to report infos, alerts and errors. Should FOP adapt these to its own feedback mechanism or should FOP expose the user agent creation to an interested developer so he can include his own hooks?

Add progress events (start/end of page-sequences, info about the placement of IDs, "underfullness" of pages etc.
