Response from the Working Group
Technique H81 provides correct semantic information for establishing the
parent-child relationships between a list item and the items in a nested
list within it. It also provides informative visual presentation of the
relationships by default in all browsers.

It is true that most screen readers at this point in time do not provide a
method by which a screen reader user can query for a parent list item. At
the current time we are only aware of this capability in the FireVox plug in
for the Firefox browser. We anticipate future support in screen readers to
recognize this parent-child relationship and enable identification of a
parent list item as they do for headings. Thus we do not feel it is
appropriate to apply technique H80 to technique H81.
