The word "In Stock" was added inside catalog.xml:
<block type="catalog/product_view" name="product.info.addtocart" as="addtocart" template="catalog/product/view/addtocart.phtml">
<action method="setData">
<name>instock_text</name>
<value>In Stock</value>
</action>
</block>
I want to rename it via Custom Layout Update XML so it would appear a different text for some products.
<reference name="product.info">
<block type="catalog/product_view">
<action method="setData">
<name>in_stock_text</name>
<value>This product is in stock.</value>
</action>
</block>
</reference>
The custom layout xml seems not working. Did I miss something on update xml?
