"data:text/html,%!foo" is handled identically in Presto, Blink, WebKit, 
and Gecko (no Trident to test in right this second, sorry), and shows 
the text.  So if the proposed syntax were applied here it would change 

Which comes back to my concern with the zip-path approach.  Is it 
supposed to work for all schemes?  Some schemes?  All-but-data:?  Only 
data: that has application/zip type?  Something else?

You're not.

The same way they do for file://: by looking at the file extension. 
This is a pretty serious issue, by the way, because file extensions 
differ by OS configuration, so we get interop issues.  Good catch.  :(
