That is <input maxlength="2" value="abc"> is not valid HTML and a validator would flag it as invalid. What UAs do with this markup, on the other hand, is defined by the UA conformance requirements, and what they do is allow a value longer than maxlength if it's specified. > or http://www.whatwg.org/specs/web-apps/current-work/multipage/association-of-controls-and-forms.html#maximum-allowed-value-length These are the UA conformance requirements in question. > The paragraph should be revised to mention and only mention that the maxlength attribute affects the validation and the user agents may prevent the user from typing more characters than the specified value. The basic question is whether a validator should flag <input maxlength="2" value="abc"> as a conformance error or not. It seems to me like it should. -Boris
