The use of <input type="file"> in this spec is out of line with HTML5  
in a number of ways. Here are some examples:

1) The proposed use of alt, title and class attributes is in conflict  
with HTML5. This is especially serious in the case of alt since alt is  
an accessibility feature.
2) Putting a URL in the value IDL attribute does not match the HTML5  
implementation requirements for this attribute.
3) It's not obvious how the "files" IDL attribute would be implemented.

I haven't yet had a chance to properly review this proposal at a  
conceptual level, but I think if it's going to use <input  
type="file">, it should be made consistent with HTM5.
