Availability schema

[kipper]

Hi, I am trying to put together rich snippets for products under
http://schema.org/Product and
http://schema.org/InStock

The name, description and image properties were easy to add but I am having a problem with currency, price and availability.

I could paste in the line

<link itemprop="availability" href="http://schema.org/InStock" />In stock

to the product page template but this would not change if the product became out of stock.

How would I add this to the "IsInStock" condition?

Try:

<actinic:block if="%3cactinic%3avariable%20name%3d%22IsInStock%22%20%2f%3e" >
	<link itemprop="availability" href="http://schema.org/InStock" />In stock
</actinic:block>
