Thanks for your response, Michael. I actually used a bad example! The actual case that I am working on is a "Product" node, where the product has a name, and a version. Two products may have the same name, but different versions. Also, a product with a newer version should have a "super product", from which it may inherit some connections.
Thanks, and have a great day.
