Hi Nicolas,
I'll be happy to pass on the CDATA information to the customer, I already suspected that this would not be a problem.
Can you already estimate when the next version of HikaShop will be released and we can use the options [is_bundle] and [multipack]? The customer would like to send the data to Google as soon as possible because of the upcoming Christmas sales. If it takes longer than two weeks, can you let me know which file I need to adapt so that we can use the feature before the next release?
