ARIA has the presentational children consept:
http://www.w3.org/TR/wai-aria/complete#childrenArePresentational

For content that is the child of an element with a role of type
"childrenArePresentational",  ARIA 1.0 says that user agents SHOULD NOT expose
them. Any button, link, etc inside a <div role=img><a href=link>text</a></div>,
would thus normally not be accessible to AT users. Pointing to that link via
aria-labelledby/-describedby would also not activate its interactivity - I
don't think ARIA has any means bring back the interactivity of such an element
- other than removing the parent role with the childrenArePresentational
effect.

Validators should warn when it detects interactive/forms associated content
inside elements with a role which has the chilrenArePresentatinoal effect as it
could mean that the author unintendedly hide some interactive/forms related
content.
