Extension:Math/Unique Ids

The attribute "id" is already live in all production Wikipedia systems. It allows linking to an individual equation that has the id attribute set.

For example the code

<math id="MassEnergyEquivalence">E=mc^2</math>

can be accessed via appending #MassEnergyEquivalence to the Page URL.

Visually no difference can be seen in the output

$E=m{c}^2$

See for example kinetic Energy
