User interface components include both "controls or accepts input"  and also
displays.

In 1.1.1 we only wanted to include the 'control' part and not the display
half of UI Components.   Hence we did not use the UI Component language
there.   We do not usually require that there be a label on each paragraph
saying that it is a paragraph - we just require that the contents be
accessible.
