I can understand that elements need to be converted to uppercase, but can't attribute names be left alone? At least Firefox, Opera and Safari do so: http://software.hixie.ch/utilities/js/live-dom-viewer/?%3C!DOCTYPE%20html%3E%0A%3Cscript%3Edocument.documentElement.setAttributeNS(null%2C%20%27Foo%27%2C%20%27bar%27)%3B%0Adocument.write(document.documentElement.attributes[0].nodeName)%3C%2Fscript%3E 21333 1 geoffers+w3cbugs 2008-07-25 12:13:04 +0000 However, the following gives it in lowercase in Firefox and Safari, and in the original case in Opera: http://software.hixie.ch/utilities/js/live-dom-viewer/?%3C!DOCTYPE%20html%3E%0A%3Cscript%3Edocument.documentElement.setAttribute('Foo'%2C%20'bar')%3B%0Adocument.write(document.documentElement.attributes%5B0%5D.nodeName)%3C%2Fscript%3E 21334 2 zcorpan 2008-07-25 12:14:43 +0000 Yeah but that's because setAttribute() lowercases -- not .nodeName. 21335 3 hsivonen 2008-07-25 12:18:15 +0000 If at all possible considering existing content, I'd love to see Element.localName not upper casing, since not uppercasing would provide for performant code that runs on both HTML and XHTML DOMs. 21343 4 ian 2008-07-25 21:08:04 +0000 ok. IE doesn't support it anyway.
