Well, there are:

- "trade secrets" expressed in the xml, which are also publicly disclosed
in the marketing material. If we say "Premium load is 3%" in a sales
brochure, and
in an XML file, there's little need to encrypt the XML. And then there are:

- "secret trade secrets" contained in the mortality-table database. Having
written a coder-decoder for those binary '.dat' files recently, you'd
probably agree that it would take considerable effort for anyone to read
them, even though the specification is available. Yet insurance companies
would generally give the tables to any broker upon request.

And anyone who understands life insurance illustrations can reverse-engineer
them anyway, given only a paper printout, so it's impossible in principle
to protect product parameters from discovery. We just want to make it
