Inheritance of aggregate

A parent product have some sub-class . The common properties of all the sub-class are put inside the parent product class .Then each subclasses contain their own set of properties and specific behaviour.

I then found that many suggest to avoid the inh
eritance of an aggregate. Instead, create a single product aggregate and create a descriptor object (which is a value object) that can discriminate between the different product subclass. So what should my product aggreagate look likes if I use the "descriptor object" approach ?

Thanks
