/**
 * Marks service requirements.
 *
 * Requirements may be specified in two ways:
 *
 * The first and preferred way is by using this annotation to private an
 * enumeration of the required service interface classses.
 *
 * Alternatively, for more complex requirements, a reference to a requires.xml
 * for this service located within its local classpath may be specified. To do
 * this, set the lookup value of this annotation to the correct location.
