Re: Maybe a solution for safer interactive epub (kids book) ?

Yeah, the "safer" here is more about the security concern of using 
javascript inside digital book (epub).

For kids book or more interactive book (quiz book or so) it is essential 
to enable javascript. However javascript is a security concern and it is 
difficult to white list or black list in detail (for example let 
javascript inside epub to be able to reach certain backend server to 
provide learning process or storing score).
