To partially give the answer to the question by myself: using the override prefix is valid at least for the 386 and later, as it is documented in the 386 programmers manual (and in [1]). But it is not documented in the 8086 / 286 programmers manuals. At least not in the instruction description. It is probably only undocumented for these CPUs? I found a way to tell JWasm to encode the override prefix: XLAT CS:0. The memory location is ignored apart from the prefix.
