Setting a name attribute on the title tag

[richardvenneman]

The Google Structured Data documentation describes that it's possible to have your site name show up as the first child of a breadcrumbs list in the search results.

This requires to add a name attribute to the title tag:

<title itemprop='name'>Your WebSite Name</title>

Looking at the gems source, it didn't exactly became clear how to achieve this. How can this be done with metamagic?

EDIT: While I know it's possible to use the JSON-LD format in a script tag, I think it would still be nice to use the title tag approach.
