undocumented $content_attributes in node.tpl.php

Yes, doesn't seem like core is placing any values into the $content_attributes (from what I could see in node.module).

Should be fixed on Drupal 8 node.html.twig first, and yes I think it should be documented since it is in the template.

Note that the Bartik copies of these templates unfortunately duplicate the documentation.

Working on it.

I'm closing this issue, marking it as duplicated, there is other issue where this is being handled: https://www.drupal.org/node/569362
