[OpenLayers-Users] How do you represent multiple layers

[Matt Priour]

Arnd is correct about the layer name list being enclosed in a single string. 
sorry for any confusion.

The "OpenLayers WMS" or "OpenLayers Mapserver" is simply a label for the 
layer in the layer switch box and should actually probably be something more 
meaningful that either of these titles.
