These values are used to define the behavior of a Relationship collection. These flags are bit flags, and may be combined to set multiple options. The absence of a flag signifies that the option is not set.

| Value | Description |
| COLLECTION_CASESENSITIVE | Specifies that the relationship type for the collection permits the use of case-sensitive names for destination objects. This descriptor is meaningful only for collections whose relationship type permits destination objects to be named. |
| COLLECTION_NAMING | Specifies that the relationship type for the collection permits the naming of destination objects. |
| COLLECTION_SEQUENCED | Specifies that the items in the collection have an explicitly defined sequence. Collections of origin objects are never sequenced. |
| COLLECTION_UNIQUENAMING | Specifies that the relationship type for the collection requires that the name of a destination object be unique within the collection of destination objects. This descriptor is meaningful only for collections whose relationship type permits destination objects to be named. |
| COLLECTION_PROPAGATEDELETE | Specifies that the relationship type for the collection requires that deletes be propagated to destination objects. The destination object is only deleted if this is the last relationship of this type that is connected to the object. |
| COLLECTION_NEWORGVERSIONSPARTICIPATE | If this flag is set, the CreateVersion method copies origin collections of this type from the predecessor creation version to the newly created (successor) version. |
| COLLECTION_MERGEWHOLE | If this flag is set, the MergeVersion method sets any origin collection of this type in the successor version to be identical to corresponding collection of either the primary version or the secondary version of the merge. If this flag is not set, MergeVersion combines the individual origin versioned relationships from the primary version and the secondary version into the successor version. For details about how MergeVersion combines the origin version relationship for inclusion in the successor version’s origin collection, see The Details of Merge BehaviorreconThe_Details_of_Merge_Behavior. |
