+/**
+ * Implements an composite context for system components. By default a system context uses the scopes specified by
+ * {@link org.apache.tuscany.core.system.context.SystemScopeStrategy}. In addition, it implements an autowire policy
+ * where entry points configured with a {@link org.apache.tuscany.core.system.assembly.SystemBinding} are matched
+ * according to their exposed interface. A system context may contain child composite contexts but an entry point in a
+ * child context will only be outwardly accessible if there is an entry point that exposes it configured in the
+ * top-level system context.
