Much of the existing application/xhtml+xml content relies on support of a variety of features such as the Macromedia Flash format and scripting. I think the litmus test here is simple: are user agents that do not support XHTML+Voice but XHTML 1.0/1.1 required to reject application/ xhtml-voice+xml content as beeing in an unsupported format? If yes, a new media type is certainly justified. If it is acceptable or even encouraged to process the content by ignoring the unknown bits then there does not seem to be considerable value in this new type. As you pointed out, W3C might at some point produce a recommendation where you can use XHTML with inline SVG content; with application/xhtml-voice+xml it's not really clear whether XHTML+Voice+SVG content should use application/xhtml+xml, application/xhtml-voice+xml, or some third type. XHTML+SVG content, unless the SVG fragments are in the <head> element and referenced via something like <object data="#svg" />, would depend even more on inline-SVG support than XHTML+Voice on inline VoiceXML support, if we need to define a new media type for each combination of XML formats, we'll quickly get a system where it simply does not matter whether one uses specialized types or just application/xml. >Are "+suffix" constructs the same as putting "+" within the subtype? A >mime type such as application/xhtml+voice+xml that maps directly to >XHTML+Voice is easy for authors to understand. I still see the "-" as >minus. What does application/xhtml-voice+xml mean but XHTML minus voice. >As you know, XHTML already doesn't have voice... And application/xml-dtd is for XML documents without DTD? Registered types with "-" typically use the "-" to separate words. As you pointed out, there aren't really types for "compound" formats yet; but it is also not clear to me whether we should have such types at all. If the CDF Working Group is really considering to have a single type for a very wide range of combinations, why can't you use that type instead? -- Björn Höhrmann · mailto:bjoern@hoehrmann.de · http://bjoern.hoehrmann.de Weinh.
