need advice on registration for YAML format

Hi, currently there is no media type registered for YAML (see <http://yaml.org/spec/1.2/spec.html>). I'd like to change that. Two questions though: 1) YAML is a text format, but it has hardwired character sets, similar to application/json (detectable via the BOM). This means, it really needs to be registered under application/*, right? 2) yaml.org isn't a standards body recognized by the IETF. So, to get into the standards tree, the canonical solution would be to move the spec into an RFC, right? An alternative would be the vendor tree (<http://tools.ietf.org/html/rfc4288#section-3.2>). So would application/vnd.yamlorg.yaml make sense? Best regards, Julian
