 * I’m not 100% clear on this, but it looks like the meta description generated 
   by AIO, isn not validating.
 * Getting this error: “Attribute itemprop not allowed on element meta at this point.”

 * Hi Steve,
 * The W3C doesn’t like Schema.org markup. There’s been much discussion about this
   on the W3.org forums over the past 3 years. You can validate Schema.org markup
   using the Google Rich Snippets Testing Tool and ignore errors from the W3C validator.
 * A lot of people prefer to have HTML code that passes the W3C validator without
   errors so we added an option to Disable Schema.org in All in One SEO Pack for
   those who want this.
 * Given that Google says that they don’t use W3C validation as a ranking factor,
   but Google does care about Schema.org markup, and given that we develop an SEO
   plugin, then we care about Schema.org markup and not markup that passes the W3C
   validator.
