RFC 2616 has this to say about MIME types:

> The type, subtype, and parameter attribute names are case-insensitive.


IE also ignores case for format strings:

>     <script>

      window.clipboardData.setData('Text', 'FAILURE');

      window.clipboardData.setData('tEXT', 'SUCCESS');

      alert(window.clipboardData.getData('Text'));

    </script>

results in an alert saying 'SUCCESS'.

Given that, would it make sense to change the spec to make format strings
case-insensitive?
