Re: makesOffer should accept Service

I'll try not to make a habit of posting lengthy code examples, I promise,
but in this case I think it's best to illustrate what I'd like to
accomplish with a multi-type item by means of the code I wrote a few days
ago. For testing purposes I have marked up the same HTML twice, once with
Microdata and once with RDFa Lite.

In Google's SDTT both examples return a single-type item where it should be
a multi-type. Yet in Yandex's SDTT the RDFA Lite version is flawless yet
the Microdata version returns an unknown-type error. Demonstrating Martin's
point that multi-type items aren't all that well supported yet.

What I find even stranger is that if you write a JSON-LD script with
exactly the same data/linkage, most tools out there produce a flawless
outcome. And this is the reason why I find it all so confusing and why I'm
weary to implement it in sites. I simply don't which output to trust even
though I think I've got the mark up right.

Anyways, here are the 2 code examples, I hope it adds something to the
discussion:
