What
Messages addressed to another session skip the usual validation: plain text is accepted without the normally-required summary, and structured object messages are rejected outright with a note that only plain text can cross sessions.

Applies to recipients addressed through the two cross-session transports; ordinary in-session recipients are unaffected.
Requires cross-session messaging to be available in the session.
Evidence
structured messages cannot be sent cross-session — only plain text
