Thanks for the explanation.
Are there any thoughts on my questions in my previous mail, which is:
If both formats have very similar sets of features, it really does not
make sense for me to have both formats available. Instead
interoperability between different systems would be better with a single
format. Better and easier interoperability could also result in a wider
distribution of encryption-usage overall. Thus I am wondering if there
are any efforts to synchronize or unite both formats? If not, which
strategies/options may be appropriate to go in this way (e.g. embed one
format into the other, using the same key parameters etc.)?
