+          Due to limitations across the web accessibility stack there is currently no mechanism to specify language and directionality for a translatable attribute separately from the element's language and directionality. This also indirectly applies to <pref>aria-labelledby</pref> and <pref>aria-describedby</pref> because the <a href="" class="accname">Accessible Name and Description Computation</a></cite> [[ACCNAME-1.2]] results in a flat string. Diverging in language or direction can also cause other accessibility problems, see [[WCAG21]].
