|add||Adds a new SelectionSet to the parent product.|

|item||Returns the specified SelectionSet object using an index into the collection.|
|itemByName||Returns the specified SelectionSet object using the name of the selection set.|
|count||Returns the number of SelectionSet objects in the collection.|
