51019835Remove a paragraph from the W3C version by request of the chairs. Add a list of differences between the versions of the spec to the WHATWG version now that there's more than a few. Add a paragraph to the W3C version mentioning this. Make it easier to keep track of what is in what version of the spec when editing.2010-06-05 05:55
