hi, is that the standard:ISO/IEC 13249-6:2006 if I investigate the data mining extension for SQL language?

Recently I noticed there are only 1-4, 9-14 parts in SQL:2008 standard: ISO/IEC 9075-1:2008. Here is: http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=45498
   why don't they define 5-8 parts in this standard?
   I also noticed there is a standard for data mining: ISO/IEC 13249-6:2006, here is:
  http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=38648.
  is that the standard if I investigate the data mining extension for SQL language?

Thanks!
