Wavelength encoding: question on lmp-mib



The LMP draft and the lmp mib draft specify the use of "wavelength" in
various places. I could not find anywhere but in the lmpTeLinkWavelength
object a description of what exactly the "wavelength" field must
contain. The description below strikes me as the ITU grid DWDM 100 GHz
spacing and better does have wavelengths with overlapping manometer
values (wavelengths 1538.19 and 1538.98 both yield 1538, 1542.14 and
1542.94 both yield 1542, etc.). 
Does that mean that this draft does not support ITU grid DWDM 100 GHz
spacing?
Or, should I change my interpretation of the text below?
Is there another place that defines the exact encoding of the wavelength
fields in LMP and GMPLS (TE LSAs and RSVP-TE objects)? 

lmpTeLinkWavelength OBJECT-TYPE
   SYNTAX        Unsigned32
   MAX-ACCESS    read-create
   STATUS        current
   DESCRIPTION
       "This value corresponds to the wavelength at
        which the Test messages will be transmitted over and is
        measured in nanometers (nm). If each data-bearing link
        corresponds to a separate wavelength, than this value should
        be set to 0."
