rubocop:disable Layout/HeredocIndentation rubocop:disable Layout/ClosingHeredocIndentation ZATCA also hashes serverside to ensure our signed properties hash is correct. However ZATCA does not format the XML to use the same whitespace needed for hashing. They generate the hash using the whitespace as you sent it, so to account for that we need to ensure we use the same exact whitespace as them.

Due to the way our SDK works, we will sadly not be able to use the same generated XML, we need to use ZATCA’s specific spacing. So we will generate the entire XML first then replace the qualifying properties block to account for this.
