A canonical comment on the case of Harm and Edeltraut Klueting
Rather, the pope doubtless dispensed him from the impediment that marriage is for the reception of holy Orders (1983 CIC 1042, 1°) and her from the obstacle that marriage is for entry into religious life (1983 CIC 643 § 1, 1°). Before these dispensations were granted, one can be sure, the couple demonstrated full awareness of the rights they were surrendering (such as that of conjugal living, per 1983 CIC 1135 and 1151). In any case, while such dispensations are not common, neither are they unheard of, even in modern times. See, e.g., CLSA, Roman Replies and Advisory Opinions (1984) 19-23.
