Protect schema.org markup in HTML editor

Description

WordPress HTML editor (tinyMCE) treats schema.org attributes like itemscope/itemtype/itemprop as invalid HTML attributes and strips them when you save the post or page content. This plugin alters this behavior and prevent the WordPress HTML editor from removing the schema.org/microdata markup.

Just install the plugin as usually and activate it. Once activated, it will keep your markup from being removed by the HTML editor. No setup required.

This is a really good plugin. I had an issue with it before adding a review to see what the outcome would be and WOW the support was fantastic. Highly recommended. This will now be a plugin I use for all my sites.

Client’s website is using a strange page builder plugin called Visual Composer. This plugin seems to strip out all of my Schema.org markup attributes. I installed this plugin, and it resolved the issues, and now my attributes are staying on the page.
