I think that's a reasonable resolution.
Another approach would be to allow "status-message" in 0x0400 responses
but warn that "client beware!", the attribute charset of this type of
response might not match that of the request. Clients could, of course,
ignore status messages in unknown charsets. I prefer this resolution
because it lets me stick helpful debug messages in responses, for
development purposes.
I think it's important to get this issue straightened out, because if
you look at the old MOD section 16 (BTW, where is it now? I don't see
it in the IIG) there are many cases that result in the
client-error-bad-request (0x0400) response.
