"Article" html tag in body of Basic Page content type: what template is rendering this? When creating a basic page, then previewing that page, here is a sample mark-up from the browser:

    &lt;article typeof="foaf:Document" about="/?q=who-we-are" class="node-30 node node-page view-mode-full clearfix"&gt;
  &lt;div class="field field-name-body field-type-text-with-summary field-label-hidden"&gt;&lt;div class="field-items"&gt;&lt;div property="content:encoded" class="field-item even"&gt;&lt;ul&gt;&lt;li&gt;&lt;img src="http://drupal-dev.ngi-dev/sites/default/files/default.jpg"&gt;&lt;p&gt;Name&lt;/p&gt;
&lt;p&gt;iOS &amp;amp; Android Developer&lt;/p&gt;
&lt;/li&gt;
&lt;/ul&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;
&lt;/article&gt;


I had pasted the basic html ul/li/dl etc in the source code view using the ckeditor, saved then viewed the page in a browser.

Don't know why a &lt;p&gt; tag was wrapped around content within established html tags but my main question is where to find what template that is adding the &lt;article&gt; tag as well as the nested structure of the extra &lt;div&gt; tags

I've looked in the template files within modules and Zen (my parent theme) but I haven't found anything yet. Where is the &lt;article&gt; tag being generated? I think that would help me find the full mark-up.
I always clean that part in node.tpl.php, that's the default template for nodes if you don't have one for each content type. So i would try changing the article tag for a div tag on that file.
You can make sure that it works cleaning all caches from your Drupal
