Added coord op parameters 8733-42. Deprecated coord op method 9622 and added replacement method 9666. For method 9624, changed name from "Affine general parametric transformation" to "Affine parametric transformation" (to match GN7-2) and for method 9623, changed name from "Affine general geometric transformation" to "Affine geometric transformation". For methods 9621, 9623 and 9624 changed method reversiblity from no to yes and added reversibility information to parameters, extended formula to cover reverse case. Deprecated datum 9312 and CRSs 5804-05; added datum 9315, CS 6511, CRS 5818, tfm 15744.
