+/**
+ * The definition of the configurable aspects of an implementation in terms of the services it exposes, the services
+ * it references, and properties that can be used to configure it.
A service represents an addressable interface
+ * provided by the implementation. Such a service may be the target of a wire from another component.
A reference
+ * represents a requirement that an implementation has on a service provided by another component or by a resource
+ * outside the SCA system. Such a reference may be the source of a wire to another component.
A property allows
+ * the behaviour of the implementation to be configured through externally set values.
A component type may also
+ * declare that it wishes to be initialized upon activation of the scope that contains it and may specify an order
+ * relative to other eagerly initializing components. For example, an implementation that pre-loads some form of cache
+ * could declare that it should be eagerly initialized at the start of the scope so that the cache load occured on
+ * startup rather than first use.
