This allows early exporters to adjust the event for later ones. This is used to lookup key values from the context if needed. Also add a Query type event which is intended to perform all event modifications but nothing else, and is used to lookup values from the context. This cleans up a weirdness where the current lookup presumes there will be an exporter with a matching mechanism.
