Thanks for checking some of the high-profile media sites!

Given that BBC and Le Figaro (the sites that use schema:headline) do _not_
use schema:name at all, and Guardian's use of both schema:name and
schema:headline to mark up the title likely reflects their own confusion
about the lack of distinction between the properties, it actually
strengthens my conviction that the conclusion should be "Use schema:name
for the article title, schema:description for the article lead, and
deprecate the use of schema:headline & schema:alternateHeadline"... because
the data shows that BBC and Le Figaro _could_ be using schema:name for the
title. They're not using schema:name for anything else, and it really is
the obvious choice that fits with the pattern we've established for pretty
much every other type.

Let's try to keep the core set of properties as slim as possible when there
is a clear overlap and no clear reason for minting new properties; that
will make it easier to provide guidance on best practices for those who are
publishing structured data with schema.org, as well as easier for those who
are parsing that data. The search engines and other processors are going to
have to continue to accept deprecated properties, of course, but the
schema.org docs could help direct new implementations towards the cleaner
