This makes sense, but note a subtle issue:

gr:ProductOrService / schema:Product is not distinct from any other type, because you can offer to transfer rights on almost anything, including a corporation, a place, etc. In RDF worlds, this does not cause a problem, because of the semantics of domain and range axioms. If you use a foo:Restaurant in the position of a product in an offer, it is simply inferred that the restaurant is also a product (which is fine and intended in the GoodRelations notion of product being a role that a thing becomes by being the object of an offer).

In Microdata and the Google tooling worlds, and with the different semantics of schema:rangeIncludes, we must (!) extend the range of schema:itemOffered and schema:typeOfGood to include schema:Service and schema:Role.

Note that an schema:Offer or schema:Demand can be linked to a product etc. either via itemOffered (simple case of just one item) or via includesObject -> TypeAndQuantityNode (for more advanced cases - e.g. bundles or quantities other than one piece of the object).

Otherwise, the validators would reject the new markup.

See above. We must do that.

Can the one submitting the respective pull request please make sure that the additional rangeIncludes statements are added to chema:itemOffered and schema:typeOfGood?
