 * A qualifier for the core coordination engine to use. Qualifiers
 * can be used to augment the protocol. For example, when enlisting a
 * participant with a transaction, it is possible to specify a caveat on
 * the enroll via a suitable qualifier, such that the coordinator knows
 * (in this example) that the participant will cancel if it does not hear
 * from the coordinator within 24 hours.
