The matching rule for attribute names and element names, [1] doesn't
match reality, see demo: [2]
* Gecko uses ASCII case-insensitive matching (as specced by HTML5)
* Trident/Webkit/Presto use Unicode caseless matching (variant).
(Legacy Firefox 3.6 behave like Trident/Webkit/Presto too.)
The differences affect @data-* and @x-* (and other extensions).
Shouldn't spec match Trident/WEbkit/Presto?
