[overlord-issues] [JBoss JIRA] (SRAMP-552) Support relationships with no target

Support relationships with no target ------------------------------------ Key: SRAMP-552 URL: https://issues.jboss.org/browse/SRAMP-552 Project: S-RAMP Issue Type: Sub-task Reporter: Brett Meyer Assignee: Brett Meyer 2.1.2 "It is possible for a relationship of a given Relationship Type not to have a target, which is termed a "relationship with no targets". In this case there is only one relationship instance with that Relationship Type for a given Source. Such relationships have a target cardinality of "0". If there is a relationship instance with a given Relationship Type that does have a target, then there CANNOT also be a relationship instance with that Relationship Type which has no target."
