Different breeders give different paperwork, you are right there is no need for a pedigree for a cockapoo, however some breeders do give copies of the parents pedigrees, or copies of health tests the parents may have had, but some breeders don't, there are no rules, so you may not get any paperwork.
You will get a vaccination card if your puppy has had a vaccination with the breeder, you may get information on the microchip if the breeder has had this done and you may get 4 weeks insurance with Barney, plus some information of when he was last wormed and treated for fleas...
I hope this helps, but there are no rules, each breeder is different
Enjoy getting your Barney ... I look forward to photos xxx
