Yeah, I know that.  I was more worried about a parser going... Ah, OK,
here's the name of the the MedicalScholarlyArticle...oh wait, no, HERE's
the name of the MedicalScholarlyArticle...oh wait no...THIS is the name of
the MedicalScholarlyArticle...etc...

Our current documentation around how to "READ" through Microdata coded with
Schema.org is fairly lackluster.  This page
http://schema.org/docs/gs.html tells
a bit about itemscope and where 1d. Embedded items shows nice closing tag
syntax, but what should a "good" parser do when it meets up with potential
snafus were the itemscope might unintentionally continue because of missing
a </p> or a missing </div> etc.   That's where my worry was founded just
quickly scanning the markup in the MedicalScholarlyArticle example and
building a parser in my mind.

We tell how to markup with Schema.org pretty well, but not about reading it
back properly.  Perhaps someone has begun documentation on that level and I
do not know about it ?

Oooo... yeah, that's a very, very cool tool... Manu get your "geek" on and
hack that thing for Microdata already ! :)
