/** Enumeration values for DigitChevronCode
* The enumeration values are generated from the SISO DIS XML EBV document (R35), which was
* obtained from http://discussions.sisostds.org/default.asp?action=10&fd=31
*
* Note that this has two ways to look up an enumerated instance from a value: a fast
* but brittle array lookup, and a slower and more garbage-intensive, but safer, method.
* if you want to minimize memory use, get rid of one or the other.
