When to add a nonstandard term vs additional guidance?

Every term we add to Compliance Dictionary needs to add value to our content. Long text strings consisting of 5 + terms that appear in only single documents that are unlikely to ever appear in another document do not add value. Instead of adding these long text strings as nonstandard terms, add the standard term in curly brackets {} in the additional guidance field.

example:

Citation text string	Nonstandard or add Additional Guidance?
procedures to guide the process of introducing changes to the environment	add additional guidance
