I am in doubt. That wouldn't even compile. But who am I to think somebody changing something like this would actually do a test compilation afterwards....

HTML isn't compiled, and unknown attributes are allowed. The best practice is to prefix non-standard attributes with data- (e.g. <div data-foo="test">) but nothing enforces that. Custom attributes can be retrieved in JavaScript or targeted in CSS rules.
