        Perhaps all three formats should be supported, and if the following
names were all valid things could be simplified further too:

                iso8601basic
                iso8601bas
                iso8601alternative
                iso8601alt
                iso8601extended
                iso8601ext

        The reason for allowing shorter names is to simplify database
management for anyone who may need to store the format name in a column for
some reason (I can't think of one now, but I get a feeling that someone
will want to do this type of thing in the future).

        For that matter, the first letter could be used instead of the first
three for the short versions.  Any thoughts on this?
