-/**
- * A <code>ContextFactory</code> that handles system component implementation types, which may be either simple, leaf
- * types or an composites.
- * <p>
- * For composite types, this factory delegates to an {@link org.apache.tuscany.core.builder.ObjectFactory} to create an
- * instance of the composite implementation and perform injection of configuration and references. Once an composite
- * instance is created, the factory will register the composite's children. This process may be done recursively in a
- * lazy fashion, descending down an composite hierarchy as a child composite is instantiated.
