Many times you want the user to make an explicit choice, rather than
just leaving whatever was already selected. What many websites do is:

<label>Choose an option:
  <select>
    <option></option>
    <option>value 1</option>
    <option>value 2</option>
    <option>value 3</option>
  </select>
</label>

Or

<select>
  <option value="">Choose an option:</option>
  <option>value 1</option>
  <option>value 2</option>
  <option>value 3</option>
</select>

It would be good if it was possible to use @required together with
these usage patterns. I don't believe that any other feature of HTML
supplies the same, or similar, functionality? While authors could do

<label>Choose an option:
  <select>
    <option>value 1</option>
    <option>value 2</option>
    <option>value 3</option>
  </select>
</label>

I think there is a reason they haven't done so so far, and I don't see
that HTML5 changes any of those reasons.

While I guess we could wait for v2 for this feature, it seems like a
glaring omission and inconsistency in the way that @required works.
