abbreviation/acronym is so commonly used in place of the whole expression that the expression is
better known by its abbreviated form.

best choice for the standard name.

/Mod
/Mod

Example 2: UNIT OPFAC NUMBER

Rule 9: Only alphanumeric characters are permitted to create the words in a data element
name, with blanks used to separate the words in the name. Hyphens are permitted only when used
to create new words necessary to represent the exact meaning of a data element. Exceptions:
Numbers may not be used as the first character of a word in a data element name.
Comment: By eliminating special characters, data designers are encouraged to describe
data element names in terms of what the data is and not how it is stored or used. This rule
improves the probability that different individuals will develop the same name for identical
data elements.
