Description

CreateSelectionLayer creates a new FeatureLayer from an existing FeatureLayer.
LayerName defines the new layer's name.
Set useCurrentSelection = TRUE here if you want to use the currently selected features on the existing layer.
joinTableNames may contain the name of related table(s) separated by commas. The existing join(s) will then be passed on to the new layer.
The DefinitionExpression parameter can be used to set a definition expression on the newly created layer but currently this will be defined at the feature class rather than at the layer level and will not show up in the UI. If you want to set a definition query on the newly created layer, it is best to use IFeatureLayerDefinition again to set the definition query after the layer has been created.
