Syntax
public class TalContextProcessorFactory : IGetsTalContextProcessor
Remarks

This factory assembles a service which uses the decorator pattern. Each individual attribute is handled by a separate decorator class (which handles just that attribute). At the centre of the decorator stack is a no-op service.

The OnErrorAttributeDecorator is special, in that it uses a try/catch construct to intercept any errors which occur in other decorators which are 'deeper' in the stack.
