Clarify what is a 'Standardization Target'

[dr-shorthair]

Probably with, or maybe through, examples

Totally agree!

Short discussion during July 23 call. Agreement that examples would be very useful. Also, there was a discussion to help all of us understand the difference between a standardization target and a standardization target type. The feature type concept was used to help clarify. Carl added examples and more informative wording to T&Ds.
