Difficult. In general there will be multiple upstream servers, even in the simplest case of a stub talking to a recursive server talking directly to authoritative servers. So there can be an arbitrary combination of upstream errors, and they might not relate directly to the QNAME, (e.g. problems with a parent zone, problems chasing down nameserver addresses). Perhaps if the upstream problems are consistent with each other, the resolver can return a single extended error code to its client; otherwise fall back to a "multiple errors" catch-all?
