I've got this figured out about half way. I'm trying to accomplish both adding a 1+ button to my site and adding organizational microdata for company name, address, phone number, etc
I have all the item types & item properties set correctly in the html body for organizational data. I also have the appropriate item properties in the head tag for the 1+ button snippets.
The confusing part is how to set the html tag above the head tag in my page. The Google 1+ setup page says:
<!-- Update your html tag to include the itemscope and itemtype attributes -->
<html itemscope itemtype="http://schema.org/LodgingBusiness">
But in the Google forum a Contributor was saying you don't actually add the itemscope or itemtype in the html tag, but rather in the div element in the page (which I do have setup correctly). She states to add the schema.org namespace:
...in the html tag. Right now my html tag is displayed as:
Do I extend the html tag to read as:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:schema="http://schema.org/">
Also, if my schema type if for a "LodgingBusiness", I have this itemscope itemtype set to such in the body div element. Do I also need to make it set as this in the html tag?
