This PR was submitted for the 4.4 branch but it was squashed and merged into the 5.4 branch instead. Discussion ---------- Add information to sub request Adding some information about _format attribute default value because I spend some times to understand why this wasn't working for me. Now I know why it was not working, _format value was html by default and I get no error message. So I just share with orther developers this little update to avoid them spending the same time. Thank you, have a nice day :) Commits ------- 4421eaa Add information to sub request

+Also, note that by default, if the ``_format`` attribute is not set in your request, the value will be ``html``.
+So, if your sub request returns something else than ``html`` (like json for instance) you can set it by setting the ``_format`` attribute on the request::

+    $request->attributes->set('_format', 'json');
