Who knew there's an <output> tag?

The template in the default theme for the 'mathematical expression' part type (known as 'jme' in code) contains a <span class="jme-preview"> tag, which contains another span marked with aria-live containing a rendering of the student's answer. I think that that <span aria-live> tag could instead be an <output> tag, which the browser will automatically mark as aria-live. The <output> tag should really have a for attribute referring to the corresponding input, but at the moment we don't give id attributes to part inputs. We should do this - the part's path combined with the question number will be a unique identifier.
