[this applies to the ContentHandler facility as developend Wikidata branch, to be merged into master soon, I hope - see https://gerrit.wikimedia.org/r/7716]

• in the Content class, it would be nice to have a getSecondaryDataUpdates(), instead of having to use getParserOutput()->getSecondaryDataUpdates(). For non-flat formats, extracting the secondary data has nothign to do with creating html output.

• getSecondaryDataUpdates() optionally takes the "previous" state. If given, it may generate updates that take into account the previous state and only update what actually changed.
