It seems conceptually problematic for something to be both semantically similar to data-* and say element names, but in practice <meta name> seems to work okay. I think there might still be some value in the registry though and enforcing requirements for the names that are shared globally (gives developers feedback as to whether their <meta> elements might get incorrectly processed by software), and maybe issuing a warning for names not registered (you might have made an unintentional typo or you might want it registered for better validation). -- http://annevankesteren.nl/
