//
// ResXDataNodeHandler.cs : ResXDataNodeHandler is the base class for the
// handler classes which are used to abstract away the different ways in
// which the ResXDataNode members behave based on the resource type / how
// it is stored in the resx file / whether it has been stored in a resx
// file as determined by tests against the .net framework.
//
// The IWritableHandler interface signifies a handler can return a copy
// of the resource in the string form it appeared in the resx file thus
// avoiding the need for instantiation.
