Taking the whole RFC 2253 encoded name leads to the problem that
insignificant white space will turn into significant whitespace
after one round of encoding and decoding:

  Original: "CN=  Gregor Karlinger" (so the value of the AVA is
  "Gregor Karlinger")

  After encoding and decoding: "CN=\20\20Gregor Karlinger" (after
  additionally de-escaping the value of the AVA is now 
  "  Gregor Karlinger")

This is the reason why I wrote "on how to encode A STRING IN a 
DName" in my proposal.
