Hi,

I've remembered an issue for rich snippet testing tool.
I was confused on those days about wrong(!) placement of itemscope.

I've tried again:

When itemscope is at the end:
<div id="rat" itemtype="http://schema.org/Product" itemscope>
 <div itemtype="http://data-vocabulary.org/Review-aggregate" itemscope>
 .
 .
 </div>
</div>
Rich snippet testing tool parse and and generate snippet properly.

when the code is:
<div id="rat" itemscope itemtype="http://schema.org/Product">
 <div itemscope itemtype="http://data-vocabulary.org/Review-aggregate">
 .
 .
 </div>
</div>
Rich snippet testing tool parses and generates snippet properly.

It's a perfectly fine question to ask!

It shouldn't matter. As I type this I see Jeni also replied :)

In general, if people have 'simple' questions like this, don't feel
bad about asking them since others are likely thinking the same thing.
It also helps standards folk understand how to improve the
documentation...
