sub / sup
sub: Render text in between sub tags in subscript.
sup: Render text in between sup tags in superscript.
All above tags require closing tags.
Usage:

Best Practice Example:
To obtain the heliocentric ecliptical longitude <i>L</i> of a planet
at a given instant, referred to the mean equinox of the date, proceed as follows.<br />
Calculate the sum <i>L<sub>0</sub></i> of the terms of
series L0, the sum <i>L<sub>1</sub></i> of the terms of
series L1, etc. Then the required longitude in radians is given by:<br /><br />
<i>L</i> = (<i>L<sub>0</sub></i> + <i>L<sub>1</sub></i>τ + <i>L<sub>2</sub></i>τ<sup>2</sup> + <i>L<sub>3</sub></i>τ<sup>3</sup> + <i>L<sub>4</sub></i>τ<sup>4</sup> + <i>L<sub>5</sub></i>τ<sup>5</sup>) / 10<sup>8</sup>.<br /><br />
To obtain the heliocentric ecliptical longitude L of a planet
at a given instant, referred to the mean equinox of the date, proceed as follows.
Calculate the sum L0 of the terms of
series L0, the sum L1 of the terms of
series L1, etc. Then the required longitude in radians is given by:
L = (L0 + L1τ + L2τ2 + L3τ3 + L4τ4 + L5τ5) / 108.
NOTES:
These tags will work in all known e-mail clients.
The W3C argument seems to be that for purpose of semantics (not to mention their usefulness),
these two tags aren't going anywhere soon.
