aria-owns
ID reference listEstablishes a parent/child relationship the DOM structure can't express, making assistive technologies treat the referenced elements as children of this one. It helps when related content must live elsewhere in the DOM, like a popup rendered at the end of the body. Use it as a last resort — it can be fragile and it reorders the accessibility tree.
