Explanatory notes¶
A non-linguistic alphanumeric string is one which does not correspond to a word in natural language. For use in a Code List. The representation property (Value) is expressed as it would be found in a data file. Multiple representations may relate to the same Category but should be expressed as separate Codes.
It should not be confused with a ClassificationItem which is a placeholder for a position in a StatisticalClassification. It contains a Designation, for which Code is a kind; a Category; and other things. For example, in 2012 NAICS (North American Industry Classification System) one Classification Item has the Code 23 and the Category construction.
