How should overflow be handled when parsing integers?
Step 8 of the parsing algorithm in both <http://dev.w3.org/html5/spec/Overview.html#rules-for-parsing-integers> and <http://dev.w3.org/html5/spec/Overview.html#non-negative-integers> doesn't mention how to handle integer overflow when interpreting the result of a sequence of base-ten integers.
Currently in WebKit we consider such overflow a parsing error. Is there any reason not to consider overflow a parsing error? Regardless, I suggest codifying the handling of overflow in the aforementioned sections.
This issue came up recently in WebKit with respect to the parsing of the maxlength attribute (https://bugs.webkit.org/show_bug.cgi?id=68981).
