I actually found part of the solution in the FAQs of the plugin (sorry for not looking at there first :P). So, I added to my function.php file the following:

$allowedposttags["time"] = array(
 "datetime" => array(),
 "itemprop" => array()
);

And then, I realized that all those “” were causing trouble, so I had to go with this:

<time itemprop="startDate" datetime="[ml_field name=schemaDate]">[ml_field name="userFriendlyDate"]</time>

Hope it helps someone 🙂

Thanks a lot Niall!
