[tdwg-content] New term needs resolution: yearOfPublication

Darwin Core Issue 84: http://goo.gl/8WkJa

This issue has not undergone public commentary.

Open Issues: Determine if there is a demand for this term. Though the term is well-described in the issue tracker, there is no evidence of a real-world need for it. There has to be a demonstrated need from more than one "independent" source for a term to enter into consideration for addition to the Darwin Core.
