[Woocommerce] How to display Product Attribute Description on product page


I have find a way to display my product attribute name on my product page. Happy with it.
I am using this shortcode

[wpbb post:terms_list taxonomy='pa_attributename' html_list='no' display='name' separator=', ' limit='' linked='no']

Now I will need to display some product attribute description somewhere in the product page.
I tried many shortcodes but didn’t find a way.

Thanks for your help.
