From the URI you provide I follow my nose to
http://uriburner.com/describe/?url=http%3A%2F%2Fschema.org%2FPerson%23this
Which as it says provides a description of the resource identified by
http://schema.org/Person#this, including the following triple :
<http://schema.org/Person#this> rdf:type
<http://www.w3.org/2000/01/rdf-schema#Class>
AFAIK, http://schema.org/Person#this is no more declared as an RDFS
class than http://schema.org/Person. Actually since
<http://schema.org/Person> is currently an information resource per
its answer to http GET, I wonder what http://schema.org/Person#this
actually identifies, since there is no actual #this anchor in the page.
In anticipation of RDFa or Microdata based resource, we use a #
terminated URI. Remember, we don't control the domains hosting these
data sets, so we simply adopted # terminated URIs based Names to
distinguish from Address of the actual Data (Resource) via usual Linked
Data patterns (where Names deliver de-reference / indirection function
and Addresses deliver address-of).
Tweaking a new URI to explicit the semantics of
http://schema.org/Person is OK, but this new URI has to be in a
namespace you control etc.
Yes, as per my comments above.
I once made a comment about an owl:shameAs pattern whereby you make pure
Linked Data in one data space that includes owl:sameAs relations where
the Object is really a suggestion/hint URI to the 3rd party data space.
First step is to start the conversation, it might so happen that
http://schema.org/Person#this will resolve to a Microdata resource, in
due course. If it doesn't, we'll pull the trigger on owl:shameAs :-)

Here is an example of an updated tweak [1] of what we did with
Google's initial foray into this realm combined with recent
developments at: schema.rdfs.org <http://schema.rdfs.org>.
Note, anyone can yank out this data, tweak, and then share
(ideally via Web in pure Linked Data form). I'll be sending an
archive to Micheal and Co. post hitting send button re. this mail.
