I'm creating this issue propose an example to explain how to use the aria-busy to track descendant elements status with aria-activedescendant that relate to ancestors elements through aria-owns.

This detailed example can help web developers keeping track of the loading state of a descendant element, which came to our attention in the ARIA-WG with issues 1956 asking us to provide additional language clarification.

I am currently drafting the new language and a code example with appropriate documentation:

Could you please provide some guidance on how to best do this?
