What about data-* attribute names? Note that the rule is: "In CSS, identifiers (including element names, classes, and IDs in selectors) can contain only the characters [a-zA-Z0-9] and ISO 10646 characters U+00A0 and higher, plus the hyphen (-) and the underscore (_); they cannot start with a digit, two hyphens, or a hyphen followed by a digit." ================================================================================ 73864 1 robin 2012-09-14 09:59:19 +0000 Same decision as https://www.w3.org/Bugs/Public/show_bug.cgi?id=16351.
