It declares a revocation key.  That is a key which may be used
alternatively to revoke the key:

:public key packet:
        version 4, algo 17, created 860451781, expires 0
        pkey[0]: [1024 bits]
        pkey[1]: [160 bits]
        pkey[2]: [1023 bits]
        pkey[3]: [1023 bits]
:signature packet: algo 17, keyid 63CB691DFAEBD5FC
        version 4, created 900530176, md5len 0, sigclass 1f
        digest algo 2, begin of digest 44 b3
        hashed subpkt 2 len 5 (sig created 1998-07-15)
        hashed subpkt 7 len 2 (revocable)
        hashed subpkt 12 len 23 (revocation key: c=80 a=17 f=3FC732041D23E9EA66DDB5009C9DBC21DF74DC61)
        subpkt 16 len 9 (issuer key ID 63CB691DFAEBD5FC)
        data: [160 bits]
        data: [160 bits]
:user id packet: "Philip R. Zimmermann <prz@pgp.com>"

So here, the DSA key identified with the fingerprint
3FC732041D23E9EA66DDB5009C9DBC21DF74DC6
may revoke Phil's key.  May be this key is not published yet; which
makes sense.

GnuPG can't handle this yet.
