I'm not sure what you mean by "degrade." It is true that XHTML+Voice follows the XHTML 1.1 modularization standard and the XML-Events, VoiceXML, and X+V markup is isolated from the XHTML by their respective namespaces. An XHTML+Voice application running successfully as an XHTML-only application has been thoroughly tested on MS Internet Explorer and Mozilla Firefox browsers. However, as noted in the Internet-Draft, XHTML+Voice user agents have special processing requirements including support for XML Events and VoiceXML. An initialized VoiceXML interpreter is a specific requirement. This mime type is limited to XHTML+Voice applications and I don't propose to change the limited designation in the internet draft. >http://www.ietf.org/internet-drafts/draft-freed-media-type-reg-04.txt >notes 'While it is possible for a given media type to be assigned >additional names, the use of different names to identify the same media >type is discouraged'.

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...
