[TMX Map Format — Tiled 1.10.2 documentation](http://doc.mapeditor.org/reference/tmx-map-format/) writes:

> \<object\>

- id: Unique ID of the object. Each object that is placed on a map gets a unique id. Even if an object was deleted, no object gets the same ID. Can not be changed in Tiled Qt. (since Tiled 0.11)
- name: The name of the object. An arbitrary string.
- type: The type of the object. An arbitrary string.

What kind of “arbitrary” is that?

It is arbitrary in the sense that Tiled does not care what you write there. However, I should probably note there that you can define the color and default properties for any type.

The name of the object is also arbitrary, but it will be displayed as a label above the object.
