   3 // because different countries or fields of practice use different methods for
   4 // coding diagnoses, procedures and supplies.  Fees will not be relevant where
   5 // medical care is socialized.  Attribues are:
   6 //
   7 // id   - the numeric identifier of this code type in the codes table
   8 // fee  - 1 if fees are used, else 0
   9 // mod  - the maximum length of a modifier, 0 if modifiers are not used
  10 // just - the code type used for justification, empty if none
  11 // rel  - a "related" code type, empty if none (for mapping to another coding system)
