User request for support for "microdata" attributes:
https://groups.google.com/forum/#!topic/google-caja-discuss/rNSAroM9MIU
Example markup I generated using the tool at
<https://www.google.com/webmasters/markup-helper/>:
<!-- Microdata markup added by Google Structured Data Markup Helper. -->
<html><head></head><body>
<span itemscope itemtype="http://schema.org/Article"><p
itemprop="aggregateRating" itemscope
itemtype="http://schema.org/AggregateRating">Testing
<span itemprop="ratingValue">123</span></p></span></body></html>
Currently, "itemtype" and "itemid" are not whitelisted; they were not included
in the original HTML5-whitelisting pass because they have URI values but should
not be rewritten by the URI policy (since they're URIs-as-global-names).
