How to find the product description container div class/attribute names?

[edvinaskilbausk]

Hi, I'm starting to develop a shopify app and it will need to somehow detect and replace product description with it's own version. My question is what kind of classes or other attributes are commonly used among themes to contain the {{ product.description }}? I want the app to work on as many themes as possible. I noticed there are things like class="description rte" and itemprop="description", but I'm not sure if it will work on all themes. Any best practices? 

Thank you:)
