* Hi, seems there is a validation error about the **itemprop** as attribute in **
meta** tag.
* Here the description
* **Attribute itemprop not allowed on element meta at this point.**
* ```
```

* That is valid markup for Google but the W3C validator doesn’t like it. If you
want to remove it then there is an option for Use Schema.org Markup under All
in One SEO, General Settings.

* Hi wpsmort,
* Thanks for the answer, I’m little confused about the fact that google allow the
itemprop where the specs say that is not standard.
* Anyway, I’ll remove it from the options.
* Thanks again.

* From what I’ve read, the W3C Validator has not been updated to support Schema.
org and RDP markup

* Uhm, within the body there are no problem with validation, I mean, if i use the
correct structure itemscope > itemprop etc…,
* Let me give you an example.
* ```
A Schema.org document
Avatar

Trailer
```
* That markup doesn’t validate if the itemscope is missed.
* Validation Response
* ```
Line 11, Column 41: The itemtype attribute must not be specified on elements that do not have an itemscope attribute specified.
```
* does this not mean that the schema.org is supported? Sorry me to bother you,
it’is just to understand.

* I’m not an HTML expert but this is an ongoing argument between HTML experts online
about whether there should be support for Schema.org markup in the validator.
All I can tell you is that we develop an SEO plugin and we ensure that the Schema.
org markup we add complies with Google’s rules because we care about Google and
making sure we comply with what they want.
