   Yeah, I suppose that would be fine, except for extremely rare cases
where the value absolutely has to be outside the pattern. The following
don't have fixed-length numeric values, for instance:

| <datalist id="math">
|   <option label="i" value="sqrt(-1)">
|   <option label="π" value="pi">
|   <option label="e" value="e">
| </datalist>

   I'm not entirely sure if they're a big enough deal to bother with.
The |label| attribute really would fix most problems. Now all we have to
do is get a vendor to implement |label| properly. :(
