+/**
+ * Implementations are responsible for creating service proxies using a particular proxy strategy. Service proxies may
+ * represent a wire between two components or a reference to a service resolved through a locate operation. When
+ * representing a wire, a proxy is injected on reference in a component implementation. In this case the proxy will
+ * implement the interface required by the reference and pass invocation messages down source- and target-side
+ * invocation chains for processing. These source- and target-side invocation chains will be derived from metadata
+ * decorating the source reference and target service definition and implementation respectively.
+ * <p>
+ * The second type of proxy will be generated when non-component client code (such as a JSP) locates a service. In this
+ * case, the proxy will implement the requested service interface but will only contain a target-side invocation chain.
