Update Layout on Attribute set
Would you like to have a custom layout for products that belong to a specific attribute set. Let's see together how you can add a layout handler for that.
As might you have noticed in Magento 2, there are some layout handlers by default that you can use, depending on product Id, product SKU and product type. The update of the layout with these handlers is happening on the Magento\Catalog\Helper\Product\View class and more specific on the initProductLayout function which initialises the layout for viewing product page.
