[IETF-PKIX] DER Encoding of Key Usage Extension?

[Anette Byskov <abyskov@xxxxxxxxxxxxxxx>]

A short question: how to encode the key usage extension with, let's say,
bit 0, 1, and 3 set. Is it

      03 02 04 D0  (BIT STRING with value '1101')
or
      03 02 04 B0  (BIT STRING with value '1011')

I know this sort of question has been asked before on this list but in
that example bit 0 and 4  were set (which is encoded 03 02 03 88 in both
cases).

Thanks,
Anette
