Description Anne 2009-01-20 10:55:38 UTC
Since due to sniffing text/html can turn out to be a feed (and actually application/xml as well) there needs to be some way for this to plug back into registerContentHandler() because otherwise e.g. cannot become a proper feed reader. Of course, browsers can give users some UI on how to let a Web page be a feed reader, but that seems more cumbersome and goes against the idea of having registerContentHandler() in the first place.

I just need to make it clearer that the registered types are compared after the sniffing. (It's already mentioned, but very subtly.)

Could also mention the handlers earlier in the navigation algorithm for schemes.

Also, should probably clarify that the navigation is restarted with the new URL if the UA is willing to just go ahead and navigate to the registered URL.

Tim also notes that this doesn't provide us with a way to do namespace-based dispatching, e.g. if a feed is sent as text/xml. Do UAs today just sniff for that case, or do they use their XML handling?
