Karl, if it doesn't matter and it's wrong, fix it or leave it out
altogether.  You'll gain the respect of your interlocutors here and the
awe of newbies reading your instructions if you don't include gratuitous
false information.  

If it *does* matter, make sure it's correct and have an authoritative
source to back you up.  That's the best way to shut your critics up.

If it does matter and you can't find an authoritative source, ask your
question here first.  Then you'll have the answer, people who can answer
you will do so without being harsh, and the jackasses on the list won't
have you as an excuse to bray.
