I have a question about Questing 2.0

Code:

[8] = {
                    [b]["complete"] = {
                        ["step"] = 255;
                    };
                    ["condition"] = {
                        ["I8AL"] = 5;
                    };[/b]
                    ["id"] = 2001568;
                    ["index"] = 2;
                    ["itemreward"] = false;
                    ["itemturnin"] = false;
                    ["mapid"] = 129;
                    ["meshname"] = "Limsa (Lower)";
                    ["pos"] = {
                        ["x"] = -44.30256652832;
                        ["y"] = 19.999996185303;
                        ["z"] = -0.31946074962616;
                    };
                    ["type"] = "interact";
                };

["complete"] = {
["step"] = 255;
};
["condition"] = {
["I8AL"] = 5;
};

Random snippet from the new limsa profile.

Could you elaborate on the Questxxxx values found in the Dev > Quest. How do you know when you need to incorporate those conditions.
