Couldn't the SGFs of diagrams please be improved?

Let me first remind you that ";" starts a SGF node, it does not end it! Now look at the second diagram of Counting Problem 1 / Solution. Its SGF reads

 (;GM[1]FF[4]SZ[19]
 GN[White takes and wins.]
 PC[http://senseis.xmp.net/?CountingProblem1/Solution]AP[GoWiki:2009]
 DT[2009-04-22]
 C[Diagram from http://senseis.xmp.net/?CountingProblem1/Solution
 White takes and wins.]
 PL[W]
 AB[ga][ia][gb][hb][jb][gc][ic][gd]
 AW[ja][ka][la][lb][hc][jc][kc][lc][hd][id][jd]
 CR[ia]
 ;W[ib]C[W1]MN[1]
 ;W[kb]C[W3]MN[3]
 ;CR[ia]
 )

Notice that

  • PC (place) should really be SO (source)
  • AP should have its own line
  • the initial comment should be at the last node (be it setup or move) since this is what it refers to (not sure if several C are standard . . . no)
  • C[Turn on "All moves with number".] in case moves follow would make sense
  • CR appears twice but should only be in the last node (be it setup or move) just like other markups (e.g. LB) for the same reason as above
  • C joins each move for not much purpose (pass could have one)
  • MN joins each move but should be only in the first node (like PL)
  • a pass (B[]) between W1 and W3 is missing (enables MN once only and lets variations the user may try, start with the right colour)
  • the second CR is preceded by a superfluous ";" (putting it into an otherwise empty node)

The improved SGF would be

 (;GM[1]FF[4]SZ[19]
 GN[White takes and wins.]
 SO[http://senseis.xmp.net/?CountingProblem1/Solution]
 AP[GoWiki:2009]
 DT[2009-04-22]
 PL[W]MN[1]
 C[Turn on "All moves with number".]
 AB[ga][ia][gb][hb][jb][gc][ic][gd]
 AW[ja][ka][la][lb][hc][jc][kc][lc][hd][id][jd]
 ;W[ib]
 ;B[]C[pass]
 ;W[kb]
 CR[ia]
 C[Diagram from http://senseis.xmp.net/?CountingProblem1/Solution]
 C[]
 C[White takes and wins.]
 )

Correction: The end of my improved SGF would have to be a single comment, quote

Only one of each property is allowed per node, e.g. one cannot have two comments in one node.
