Also, when using a composite tuple, the value is nil instead of false:

user=> 
(let [db (d/with-db system/conn)
        schema [#:db{:ident :foo,
                     :valueType :db.type/boolean,
                     :cardinality :db.cardinality/one}
                #:db{:ident :bar,
                     :valueType :db.type/boolean,
                     :cardinality :db.cardinality/one}]
        db (:db-after (d/with db {:tx-data schema}))
        more-schema [{:db/ident :some-composite-key
                      :db/cardinality :db.cardinality/one
                      :db/valueType :db.type/tuple
                      :db/tupleAttrs [:foo :bar]}]
        db (:db-after (d/with db {:tx-data more-schema}))]
    (u/pprint (:tx-data (d/with db {:tx-data [{:foo true
                                               :bar false}]}))))
