The attributes changes were left out of Clang 17. Attributes that used to take a string literal now accept an unevaluated string literal instead, which means they reject numeric escape sequences and strings literal with an encoding prefix - but the later was already ill-formed in most cases. We need to know that we are going to parse an unevaluated string literal before we do - so we can reject numeric escape sequence, so we derive from Attrs.td which attributes parameters are expected to be string literals.
