HTML validation errors using Facebook RDFa doctype & meta property

I followed this stack, Html validation error for property attribute, and used the RDFa doctype to work with the Facebook Open Graph.

My question is, how can I get th开发者_开发技巧e HTML Validator to work with this line of code (required):

<map id="Map" name="Map">

Currently the validator fails because "there is no attribute 'name'".

Here's my page and validator error.

The "name" attribute in XHTML has been deprecated in favor of the "id" attribute for the map tag.
