Yes, this was actually discussed in a thread in April:
http://sourceforge.net/mailarchive/message.php?msg_id=48070F90.60609%40matrixscience.com

In the last post David Creasy came up with the following list:

centroided
profile
   linear
   quadratic
   higher order polynomial
   FT
   other
      contiguous
      missing zeros  (thresholded)
      multiple calibration coefficients
      multiple segments (stitched psd)

I don't know if this discussion continued elsewhere, but anyway it would 
be nice to be able to have a CV term group for m/z spacing: linear / 
quadratic etc,
and also possibilities for annotating contiguous / missing zeros.
ms-mapping rules could then be added for 'm/z spacing', etc, for profile 
spectra.
