[1] (XMLHttpRequest 2) Third proposal for cross-site extensions to XMLHttpRequest from Ian Hickson on 2006-06-06 (public-webapi@w3.org from June 2006) http://lists.w3.org/Archives/Public/public-webapi/2006Jun/0012.html

PS. I have decided that the Cross-site Extensions to XMLHttpRequest specification should have the acronym XXX. I figure if I'm going to be involved in a spec that has an X in the name, I'd better go the whole way.
