About half a year ago I wrote a file "accReg-Defs.lyinc". It contains 
definitions for all accordion registrations that can be found on my 
girlsfriend's "Hohner Morino V".

I don't known, whether my solution is according to all existing lilypond 
standards, but it works fine for me using Lilypond 2.2.5 using the 
CygWin environment. If there is any interest, I will make the file 
available to everyone. Just inform me, how to post it.

The accordion registrations like they are at the moment are defined as 
skip notes of zero length with an appropriate markup attached to it. An 
example definition:

  accBasson = \notes {
    s1*0^\markup {
      \combine
        { \musicglyph #"accordion-accDiscant" }
        { \raise #0.5 \musicglyph #"accordion-accDot" }
    }
  }

The defintion is used as follows:

  \score {
    \notes {
      c d e f
      \accBasson c d e f
    }
  }

Of course, the definitions can be changed to work as normal markups. The 
altered definition and the usage after changing it is shown in the 
following example:

  accBasson = \markup {
                \combine
                  { \musicglyph #"accordion-accDiscant" }
                  { \raise #0.5 \musicglyph #"accordion-accDot" }
                }

  \score {
    \notes {
      c d e f
      c^\accBasson d e f
    }
  }

Probably, this way of defining the registrations might be slightly 
better in terms of collision detection. I never evaluated this problem 
as I use the "extra-offset"-property for fine-tuning the positioning of 
the registrations.

I hope, I replied in the right manner as this is my first posting on a 
newsgroup and I had some prblems on finding out how to use the 
lilypond-user-group.

Kind regards,
