Description Roman Romanov 2012-03-12 23:45:45 UTC 
I try to use XHTML5 with microdata and have error:
"Attribute itemprop not allowed on XHTML element meta at this point."
Happend on:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
 itemscope="itemscope"
 itemtype="http://schema.org/Person">
  <head>
<meta name="author" itemprop="name" content="Some Name" />
<meta name="description" itemprop="description" content="Some Description" />
But specification "A vocabulary and associated APIs for HTML and XHTML"(http://www.w3.org/TR/html5/microdata.html#names:-the-itemprop-attribute)
say:
"Every HTML element may have an itemprop attribute specified ..."
Comment 1 Michael[tm] Smith 2012-03-13 05:46:34 UTC 
The microdata spec defines some further restrictions -

http://dev.w3.org/html5/md/#content-models

"If a meta element has an itemprop attribute, the name, http-equiv, and charset attributes must be omitted, and the content attribute must be present."

So you need to omit the name attribute
