Re: Inverse Properties in Microdata:, was Re: schema.org update, v1.8: added WebSite type; broadened isPartOf to relate CreativeWorks

I've made a document (
https://www.w3.org/wiki/WebSchemas/ChainingLayoutElements) with a bunch of
markup examples, in microdata, in an attempt to help with the overlapping
discussions about: @itemprop-reverse, hasPart - isPartOf, and the chaining
of WebPage to WebSite and WebPageElements, and the Things they (may)
contain (mainContenOfPage / mainEntity).

If any of you want to have a look/shoot at it and/or suggest additions, by
all means, please do.

I hope it helps.   :)
