Both WebKit and Gecko implement DOM L&S' LSProgressEvent's position and totalSize attributes on (some?) XHR ProgressEvents. This should be specified, either in XHR or in PE.
As they cannot remove it?
I'd prefer to remove it, but I'm not sure how feasible that is. Note that I think that the attributes aren't simply synonyms with .loaded and .total as iirc they include header size.
