May I ask why? I thought the main feature of Microdata was its simplicity. Reverse properties are not exactly the simplest thing as this thread has shown. So why add them to Microdata? Why can't we simply recommend people to use RDFa for such "advanced" use cases? Do we want to evolve both formats in the future?

Don't get me wrong, I'm not against adding this feature to Microdata at all. I'm just curious to understand the motivation and reasoning behind this effort.
