Hi Martin, I searched around a bit and found this document: http://www.adrc.asia/publications/TDRM2003Dec/19_MR.%20SATORU%20NISHIKAWA.pdf That document introduced another classification, which I believe is different from what can be found in the CAP document. I wonder how the two relate to each other. I suspect that there will never be an agreement on the categories and the only way to go with this is to * just define a top level service * pick a few sub-level services * provide extension points.
