Hi, http://www.ietf.org/internet-drafts/draft-hoschka-smil-media-type-12.txt is a bit old by now, but I don't think application/smil should be COMMON as it does not use the +xml convention for XML media types. Instead, it should be OBSOLETE and application/smil+xml, defined in the same draft, should be used instead. http://www.w3.org/TR/2005/PR-SMIL2-20050927/ only has application/smil (which is not currently registered), it should use application/smil+xml and point out that application/smil is obsolete, assuming that the +xml version will be registered in the not too distant future. regards, -- Björn Höhrmann · mailto:bjoern@hoehrmann.de · http://bjoern.hoehrmann.de Weinh.
