/**
* Optional, but typically used, annotation for service decorator methods, used to define which services the decorator
* applies to. This annotation defines a number of <em>patterns</em> that allow services across multiple modules to be
* selected. A decorator is applied to a service if any of its patterns match the service.
*
* TODO: Describe pattern glob-match syntax
*
* When the Match annotation is not supplied, then the decorator only applies to a single service: the service whose id
* matches the decorators id; that is, method <code>decorateMyService()</code> would decorate only the service provided
* by the <code>buildMyService()</code> method, within the same module.
