You can delete a collection member by calling the
DELETE_MEMBER procedure and referencing the desired collection member by its sequence ID. Note that this procedure leaves a gap in the sequence IDs in the specified collection.
You can also delete all members from a collection by when an attribute matches a specific value. Note that the
DELETE_MEMBERS procedure also leaves a gap in the sequence IDs in the specified collection. If the supplied attribute value is null, then all members of the named collection are deleted where the attribute (specified by
p_attr_number) is null.
