Re: validThrough and validUntil

Perhaps prematurely, I opened an issue about this earlier 
https://github.com/schemaorg/schemaorg/issues/2030

If the difference is that Through is inclusive and Until is not then, 
(a) that should be in the definition, and (b) the two properties should 
be attached to the same schema.org types (as Michael says).
