https://quicwg.org/base-drafts/draft-ietf-quic-transport.html#long-header

> Long headers are used for packets that are sent prior to the establishment of 1-RTT keys. Once both conditions are met, a sender switches to sending packets using the short header (Section 17.3). 

What are these "both conditions"?

Also, can there be made a clear statement such that: all packets prior to Application PN space use long headers, and all packets in application PN space uses short headers?

And, the table of frames with section references, would it make sense to add PN space columns with an X where a frame is applicable?
