reference Scale
The reference scale for the layer. The reference scale of the layer is the scale at which a client should view the layer for the text to appear at its authored size.
If the client changes the viewing scale, then text will grow or shrink to keep a consistent size on the map (not the screen).
For a valid layer, the reference scale will always be a finite value, greater than zero. Until the layer is loaded, the reference scale will be zero.
