Long description of product in schema.org/review

Hello,

if you follow indications in http://schema.org/Product you have place just
for a short description and then http://schema.org/Review you have customer
reviews.

What if I have a product page where I want to do a long "editorial" review,
then display many features of the product in table or similar and finally
also allow readers/customers to make reviews? How to tag the editorial
review and make it stand over the customer reviews??

Thanks
