Hi All,

I've written up a BIP draft for MuSig2 PSBT fields. It can be viewed at=20
https://github.com/achow101/bips/blob/musig2-psbt/bip-musig2-psbt.mediawiki=
.

This is based on this gist from Sanket:=20
https://gist.github.com/sanket1729/4b525c6049f4d9e034d27368c49f28a6.=20
There are a few notable differences:
- The participant pubkeys field is keyed by only the aggregate xonly key
- Participant pubkeys are compressed pubkeys rather than xonly.
