// This file contains most of the interfaces that allow System.Web, Venus, and 
// Whitehorse to customize configuration in some way.
// The goal of the design of customization is to only require other MS assemblies
// to create an instance of an internal object via Activator.CreateInstance(), and then
// use these objects through *public* System.Configuration.Internal interfaces. 
// We do not want extenders to have to use reflection to call a method - it is slow,
// not typesafe, and more difficult to promote correct use of the internal object.
