            Request 1:

            GET …/container

            Response 1:

            [

                {"id":123, "weight":100, "parts":[{"id":1, "color":"red"}, {"id":2, "color":"green"}]},

                {"id":456, "weight":500, "parts":[{"id":3, "color":"green"}, {"id":4, "color":"blue"}]}

            ]

          #Request 2 in EXAMPLE from clause 4.3.2 probably wrong, since "," should be used after opOne (eq), "." is used
