OK you are really bending what you would use rules for, I really wouldn't
recommend that. flattening the object model would allow you to write rules
over it, but as it stands, its just going to be a bit difficult for you.

        catalogObject : CatalogObject( )

        *eval*( catalogObject.getElementValue("depth") == *null* ||
catalogObject.getElementValue("depth") == "" )
