Data types and Controlled Vocabulary

• There exists a data type definition (used to
  describe the format of each data element) or
  predefined bounded vocabularies for each element
  in the AICC CMI Data Model.
• These definitions further define how the API and
  data model must be implemented.
• All of the data types have the first three
  characters of CMI to clearly indicate that
  they are data types that may be unique to the
  AICC CMI Data Model.
