Note that in order to be friendly to AT users, you would need to
sprinkle some ARIA attributes on <my-calendar>.

This is another problem if extensions start being used on the public
web. They carry no inherent semantic meaning, which means that unless
you take extra precautions (like ARIA), you are creating inaccessible
pages.
