It is in there.  A while back there was a good bit of discussion
around the problem of subpackets, including notations and policy URL.
There was also some concern about future expansion and the need for
adding new flags each time OpenPGP added a new packet type.  It ended
up as a single generic way to list any subpacket type.  This lists all
possible subpackets:

gpg --with-colons --list-options show-sig-subpackets --list-sigs

This lists notations:

gpg --with-colons --list-options show-sig-subpackets=20 --list-sigs

This lists policy URLs:

gpg --with-colons --list-options show-sig-subpackets=26 --list-sigs

This lists both notations and policy URLs:

gpg --with-colons --list-options show-sig-subpackets=\"20,26\" --list-sigs

The format of the "spk" record is documented in doc/DETAILS.
