Signature Subpacket format questions

[Edwin Woudt <edwin@xxxxxxxx>]

While implementing V4 signature support for a Java OpenPGP library, I
encountered a few things with some Signature Subpackets that were not
immediately clear to me. I would be very grateful if someone could
answer these questions:

* The format specified for both 5.2.3.18. 'Preferred key server' and
  5.2.3.20. 'Policy URL' is 'String'. Is this string terminated by a
  null value, like 5.2.3.14. 'Regular expression', or not?

* What is the format for 5.2.3.22. 'Signer's User ID'? A String like in
  the previous question?
