### Why is this important?
If the content of a `<frame>` is not HTML, it may not be accessible.
For example, if the source of the `<frame>` element is an image file, assistive technology cannot read the content because `alt` text cannot be added to the image in the `<frame>` source.
The user opens the frame and hears nothing or perhaps the name of the image file.
The `<frame>` element is obsolete and ideally should not be used.
When used, the frame source must be accessible.

### What to do
* HTML `<frame>` is obsolete, if possible avoid its use
* **Or**, verify that interactive content inside the frame is accessible by keyboard
* **And**, verify that content inside the frame can be accessed by assistive technologies, such as a screen reader
