To avoid changes on CSS side in current proposal 
this is achived via special HTML parsing rules that 
treat adjacent indices as stacked.

<sup>1</sup><sub>2</sub> => <stack><sup>1</sup><sub>2</sub></stack>

Parsing rules does not apply to XHTML version however.

They already are expected to stack over each other.
