Section 3.3.5. says:

         Attribute Type                 Value        Attribute Format
      --------------------------------------------------------------
      RESERVED                           0-13 Key Length (in bits)
      14                 TV RESERVED                           15-17
      RESERVED TO IANA                   18-16383 PRIVATE USE
      16384-32767

   Values 0-13 and 15-17 were used in a similar context in IKEv1 and
   should not be assigned except to matching values.  Values 18-16383
   are reserved to IANA.  Values 16384-32767 are for private use among
   mutually consenting parties.

   - Key Length

      When using an Encryption Algorithm that has a variable-length key,
      this attribute specifies the key length in bits (MUST use network
      byte order).  This attribute MUST NOT be used when the specified
      Encryption Algorithm uses a fixed-length key.

It should say:

?

Notes:

I do not understand anything.
Therefore I cannot offer a better formulation.
--VERIFIER NOTES--
No alternative text was proposed. Note that I did forward this to the authors of draft-ietf-ipsecme-ikev2bis.
