Topic 5.E Is a video considered changing content?

I am still struggling to understand the 5.E Change Notify Form question on the incremental.

I understand this tests if the user is notified that selecting something will change the content on the page. However, I am confused about what is considered a sufficient description when referring to the interface element.

1. Does the element need to be named a button/radio?
2. Is playing/muting a video considered a page change?

ANSWER:

1. Buttons are specifically tested for forms in 5.D that they do not initiate an unexpected change in context. Interface elements can be a wide variety of things: fields, radio buttons, check boxes, read-only fields, and multi-select lists. All of these are content tested for 5.E, 4.1.2-change-notify-form.
2. The content of the page does not change with play or mute. The play/pause button for a media play are tested under links/forms in Topic 6. Video controls would be tested in 17.D for Synchronized media in the example described in the question.
