Remarks
The DeleteRelationshipsForObjectSet method is used for removing all relationships in a particular relationship class for the specified set of objects.
This method works in the same way as the DeleteRelationshipsForObject method, except on a set of objects rather than a single one. If a cursor is used to populate the set with objects, ensure that a non-recycling cursor is used.
This method should be called within an edit session.
//e.g., nameOfRelClass = "relclass"
// nameOfOriginTable = "origintable"
