Property Value

Intended to allow the marker to be identified, for example, so that it can be associated with properties that is stored elsewhere.

Note that there is no guarantee that this property uniquely identifies a specific marker instance. Even if the id is originally unique, the marker may be duplicated during content processing operations, which causes cloned instances to use the same id.

This property may be null.
