Which language is supposed to be used on Special:CreateItem?
The field labels are localized, but it's not quite clear in which language the values are supposed to be written. Is it supposed to be some common agreed language (like English) or the user's interface language?
Given that the form is localized, the expected answer is "the user's interface language". If it's true, then the proper lang and dir attributes must be applied to the fields.
If it's supposed to be English or some other language, which is not the same as the user's interface language, then it must be clearly stated in the form.
