Remarks

The valid property indicates if the layer is currently valid.  Layers that reference feature classes are valid when they hold a reference to a valid feature class.  The property does not however validate the integrity of the feature classes reference to the database. Therefore, in rare situations if a datasource is removed after a layer is initialized, the layer will report itself as valid but query attempts to the data source will error due to the lack of underlying data.
