I'd guess it would be nice for a front end to get a hint that something
unusual happened in case it wants to have some kind of special handling
of such cases (like localizing the error message).
A separate field error="...", or perhaps value="<error reading variable: %s>"
as suggested with an additional field iserror="1" would be easier to handle
than checking the "value" field for well-known strings, especially if such
content could be legal output in some cases, too.
[But take this with a grain of salt, I/we haven't used MI for data retrieval for a
while now, so maybe there are already enough hints in the output nowadays.]
