This looks strangely familiar ;-).  From RFC 5931:

 The following is the initial layout for the password pre-processing
 method registry:

   o   0x00 : None

   o   0x01 : RFC2759

   o   0x02 : SASLprep

   The Prep field is 8 bits long, and all other values are available
   through assignment by IANA.  IANA is instructed to assign values
   based on "Specification Required" (see [RFC5226]).

Is there some good reason not to use the IANA Registry already
established
(http://www.iana.org/assignments/eap-pwd-parameters/eap-pwd-parameters.xml#eap-pwd-parameters-4)?
