In draft-ietf-quic-tls.md:

>  
-- CONNECTION_CLOSE frames signaling application errors (type 0x1d) MUST only be
-  sent in packets at the 1-RTT encryption level.
+- ACK frames MAY appear in any packet number space, but can only acknowledge
+  packets which appeared in that packet number space.

This text is weird in light of the following graf that says that ACK is not permitted in 0-RTT. I would add a parenthetical "(however, as noted below, it is not possible for ACK frames to be sent in 0-RTT)"
