Right. It took me a while to figure out why "item" seems to have special
meaning in the schema.org docs, but I eventually realized that the usage
of "item" is more generally tied to the semantic types being marked up
(which explains the microdata itemtype / itemscope property names and
the references to "item" in the RDFa spec, for example). For those
coming to schema.org without that broader context, then, I'm concerned
that "item" is going to strongly suggest material goods rather than the
more inclusive products-and-services. (But perhaps that's based too much
on my own thick-headedness!)

I, too, admit to feeling a little discomfort about the heavy reliance on
examples in the definitions. It might be interesting to put together an
experimental draft that separates the inline examples from the
definitions, at least for a subset of the vocabulary: I suspect that it
would end up pushing us to strengthen the definitions in the long run.

If the brief examples were kept adjacent to the definitions in the docs,
then I think it would assuage Thad's concern that the examples are
extremely useful (a concern I also share).  But in the short-term, I
would be happy if we could just clarify the intended usage for what
already exists in the vocabulary using the current structure.
