/**

 * off of the relationship ID that ends up on the end of the Delete URL, like this - /alfresco/service/cmis/rel/assoc:363.
 * Left to its own devices, Relationship.delete() will end up issuing a URL like /alfresco/service/cmis/rel/363, and Alfresco
 * will barf. This will hopefully be fixed in Alfesco 4.x.
