+EDIT 2019-03-02: _A small but important precision on Full Stanza Encryption.
+I did write "what is usually called", because it does not actually consist in
+encrypting the full stanza. The server still needs to see routing information,
+as well [messages hints][XEP-0334] (e.g., `<no-copy/>` or `<no-store/>`)
+designed for the server rather than the final recipient. A better name might
+be "Arbitrary Extension Element Encryption" (thanks Flow.)_
