I think column is an optional element, so if it were spelled incorrectly,
I'm
guessing you should treat it as if it wasn't there, and use the default
column
value, which sounds like what you've done.

If it was a mandatory item that was spelled incorrectly, then I guess you'd
have
to reject the message, but as column is optional, I don't think rejecting
the
message is necessary.

Instances can be between 1 and 16 bytes long.
So I guess you could allocate a fixed 16 bytes and just use zero padding
for
instances that are under 16 bytes?
