As it happens, in my experience Opera 6 and 7 handle application/xhtml+xml 
better than Gecko. (Aside from a minor bug in Opera 6 that means the 
user has to refresh the page before the style sheet will be applied)

HTTP_ACCEPT includes "*/*", thus Opera indicates that it accepts 
application/xhtml+xml.

| b) it is treated and parsed as XML (including a check for well-formedness)

Why c? 

Does a browser have to put image/png at a higher priority than 
image/jpeg to indicate that it accepts PNG images? Does it need to put 
audio/mp3 at a higher priority than application/pdf to indicate that it 
accepts MP3 audio?

To indicate that a browser accepts application/xhtml+xml, all a browser 
must do is put one of these in the Accept header:

	a) application/xhtml+xml
	b) application/*
	c) */*
