 * Can be specified on an aspect to ensure that particular types must be accessible before
 * the aspect will be 'activated'. The array value should be a list of fully qualified
 * type names as strings, for example "com.foo.Bar". Useful in an aspect library that
 * includes a number of aspects, only a few of which should ever be active depending
 * upon what is on the classpath.
