Notice how it reports an error if there is a tab or newline character, but continues anyway? The specification says that A validation error does not mean that the parser terminates and it encourages systems to report errors somewhere . Effectively, the error is ignored although it might be logged. Thus our HTML is fine in practice. ↫ Daniel Lemire This reminds me of the “Email is easy” quiz .
