mm1: Here is an extract from CCTS v2.01 if this should help:    (03)

"The representation of the information in a Core Component whose Core 
Component Type is Code. Type should use a standard issued by a recognized
standards body, whenever a standard exists. If international standards 
are not used a business driven justification shall be provided."    (04)

I've also attached a paper from Mike Adcock, now deceased, who wrote 
about the quandry about code and identifier. A lot has been done and 
debated since this was produced in June 2002. As a final note, if it is 
a real world object, the representation term is used instead (if memory 
serves me correctly) not the Code. Type. Thanks.    (05)
