Either it is valid (which seems to imply that percent-escape-processing happens early) or it is not (if percent-processing happens late). If it is valid then a validator has no business warning about it. This would be a completely different case from, say, t=10,8, for which a validator could conceivably warn that it is syntactically valid, but probably semantically incorrect.
