Subject: [openpgp] Additional (En|De)cryption Subkey

Hello,

I noticed a new key flag appearing in RFC4880bis-05, the ADSK flag.
However, I am struggling with the meaning and how it is envisioned to
be used.  The Information in the RFC is scarce, and the corresponding
commit message merely says "Define an Additional Encryption Subkey
flag".

% grep ADSK draft-ietf-openpgp-rfc4880bis-06.txt
  0x04 - This key may be used as an additional decryption subkey (ADSK).
   The ADSK flag helps to figure out an encryption subkey.

Would you be so kind to clarify this part of the RFC?

Thanks,
Justus
