[tdwg-content] Darwin Core Proposal - term content recommendations to comments

IAO:example of usage is widely used with object properties. I don't know
how often it is used with data properties, but I don't know is any reason
it could not be.

I will file an issue about the truncated definition of iao:example of usage.
