Remarks
This property identifies the layer to the server. Each layer ID must be unique within the LayerCollection. The ID can be any combination of alpha and numeric characters. Do not use spaces in the ID. Do not use any special characters.
Set IDs only for layers you create as selection layers, dynamic layers, or acetate layers. Do not change the ID for layers in the map service. If you change the ID of a layer in the map service, the server will ignore any other settings for the layer, such as visibility, renderer or filter.
