There is also the issue that changing the parsing rules around <li> is 
difficult. For example, the following:

    <ol>
     <lh> Fruit
      <li> Apple
      <li> Pear
     <lh> Vegetables
      <li> Carrot
      <li> Celery
    </ol>

...looks like it should work, but in practice the <lh> element for 
Vegetables would end up inside the Pear <li> element, and changing that 
would likely be problematic.

Given the variety of alternatives to <lh> that already exist in HTML4 and 
that have been introduced in HTML5, I do not propose to add <lh>.
