Remarks
AuthoringScope is used to contain the requested information from a parsing operation.
Notes to Implementers:
This class must be implemented in a derived class. If you support either IntelliSense or the Go to options (Go to Declaration, Go to Definition, and Find All References), you must implement the methods on your version of this class; otherwise, you can return a null reference (Nothing in Visual Basic) values from all methods. However, you must always return a non-a null reference (Nothing in Visual Basic) instance of your AuthoringScope object if the parse operation succeeded, even if you return a a null reference (Nothing in Visual Basic) value from all methods.
Notes to Callers:
An instance of this class is returned from a call to the ParseSource method that in turn is called on a background thread from the BeginParse method is called from many methods in the Source class and for many reasons.
Examples
An example implementation of this class is the PythonScope class in IronPython Sample.
