This list comes from section 2.7.2 of the manual:
"The 'type' slot qualifier is accepted but not currently enforced by
Jess; it specifies what data type the slot is allowed to hold.
Acceptable values are ANY, INTEGER, FLOAT, NUMBER, ATOM, STRING,
LEXEME, and OBJECT."
As the manual says, "type" isn't enforced -- in fact, Jess doesn't
even look at the symbol you supply. Feel free to use DATE or FOO or
anything else -- it will have no effect.
