//  The traditional method of asking for all of the components recursively//  does not work if you are looking for reference-only components,//  because they are not retured when you ask for the children.////  Also, asking for the AssembliesGeneralPropertiesBuilder.ReferenceComponent //  Property  does not work in versions earlier than NX12.////  The workaround is to cycle for components the old-fashioned way,//  and then ask whether each one has the REFERENCE_COMPONENT attribute.////  If you have multiple occurrences of a given component in the assembly,//  each one will be reported.
