Thanks for your information.
However, I've also followed the Common Criteria for a few years, and
some of facilities came from its requirements. The "security_context"
system column reflects the requirement of labeled import/export, for
example. Don't worry.

Let's move our discussion into its implementation in the upcoming
CommitFest. It's a good time now.
