how about allowing decimals, where by default "1" implies "1.0"? :

 <input tabindex="1" />
 <foo tabindex="2">
    <input tabindex="2.1" />
    <input tabindex="2.2" />
 </foo>
 <input tabindex="3" />

This also allows you to quickly associate the grouping of an input by
it's value when viewing the source:

<table>
<tr>
   <td><input tabindex="1.1" /></td>
   <td><input tabindex="2.1" /></td>
</tr>
<tr>
   <td><input tabindex="1.2" /></td>
   <td><input tabindex="2.2" /></td>
</tr>
<tr>
   <td></td>
   <td><button tabindex="3" /></td>
</tr>
</table>

obviously the above example could have just used tabindex 1 through 5
but you get the point
