  Because RFC 2038 used "string" for both printable and non-printable attributes.  That was wrong, so I made FreeRADIUS use "string" for printable ones, and "octets" for binary ones.

  The IETF didn't listen to me (at the time), and chose to use "text" for printable attributes, and "string" for binary ones.  So they're wrong.

  We don't use the IETF names, and won't use them.  The IETF uses "octets" when referring to binary data everywhere else.  And using "string" is wrong, IMHO.  But that can't be changed now.
