I think operating over files is a great example of how useful these operations can be and frames the problem into a far more real-world scenario for html over the way these operations are usually discussed in terms of XML and business processing.

I'm not sure if forms can support other media type encodings. The file input can specify an 'accept' attribute but i don't even think this would be sent with the file data under normal form encodings.
