Hi Bjoern,

You said that RDF/A was dropped, and I replied that it wasn't. You then said
that there had been insufficient explanation of the motivations for RDF/A,
so I gave you some. You now say that RDF/A doesn't do the job...I hope
you'll forgive me if I don't chase your moving goalposts any more on this --
especially since you warned me in your first email that you are unlikely to
be convinced ;)

Best regards,

Mark
