Step 7 in the algorithm for open() [1] says to reject URLs in  
unsupported schemes. Is there a way to find out supported schemes? The  
spec says nothing normative about schemes other than HTTP (what about  
HTTPS). Therefore, is it fair to assume that filedata uris are not  
supported in XHR and that any browser doing otherwise is doing a favor?
