Remarks

A WMSMapLayer is a container of WMS layers.  There are two ways to create a WMSMapLayer:

1. Add all the vailable WMS layers using EngineWMSMapLayerFactory.

2. Add selected or individual WMS layers to the WMSMapLayer through these steps:

� Set the URL in WMSConnectionName
� Use IDataLayer to connect the WMSMapLayer (now empty) to the WMSConnectionName (which now has the URL for connecting to the WMS service). 
� Get the WMSServiceDescription from IWMSMapLayer (WMSMapLayer is now connected to the service and has access to the service the capabilities, this includes a list of WMS layer descriptions)
� Iterate through the WMSLayerDescriptions to find the WMS layer description or layer descriptions that you are interested in
� Use the CreateWMSLayer method to create a WMSLayer inside the WMSMapLayer
