If we don't require "poster" to be case-sensitive, then some existing
software will do the wrong thing.
If we require it to be case-sensitive, then people who type it wrong
will not have the right thing done (though their own software should
warn them).
I'd say that it SHOULD be generated in lower case, and MAY be accepted
(by the reader's software) in any case.
