It's one possibility, better than others. But I'd like to push it even further, using the English string as the tag.
Example:
<div id="right">
<div id="info">
<h4>Outerra Engine Alpha Tech Demo and Outerra Game</h4>
<p>This is the first <i>alpha</i> release of technology demo of the Outerra Engine, coming with the whole planet Earth rendered in real-time seamlessly from space down to the ground, with full visibility and a high detail.</p>
<p>Together with the demo we are launching a pre-alpha version of the first game that's running on the Outerra Engine.</p>
<p><b>Anteworld</b> (Antecessors' world) is a world-building game on a massive "true-to-life" scale of our planet. Arriving aboard a returning interstellar colonization ship built in the Golden Age of Mankind, and discovering civilization and humanity vanished from our home planet, players must rebuild the civilization - exploring, fighting, and competing for resources while searching for clues to the disappearance of humanity.</p>
<p>Pre-alpha version of <b>Anteworld</b> can be bought at half the final price. Early adopters will have access to regular game builds released during alpha and beta stage, and to the final game once it is released. Anteworld is also a technology test bed for the Outerra engine, first to come with any new Outerra technology developments.

It would get extracted into the default map:
1: Outerra Engine Alpha Tech Demo and Outerra Game
2: This is the first <i>alpha</i> release of technology demo of the Outerra Engine, coming with the whole planet Earth rendered in real-time seamlessly from space down to the ground, with full visibility and a high detail.
3: Together with the demo we are launching a pre-alpha version of the first game that's running on the Outerra Engine.
4: <b>Anteworld</b> (Antecessors' world) is a world-building game on a massive "true-to-life" scale of our planet.

This will be used to create a localized version:
1: Outerra Engine Alpha Tech Demo i Outerra Gra
2: To jest pierwsze wydanie ...
3: Zaciekaj tchurzu, bedziesz zamordowany!
4: Zaciekaj tchurzu, bedziesz zamordowany!
5: Zaciekaj tchurzu, bedziesz zamordowany!
The same tool that extracted the strings will be able to create localized versions using the localized table and the original, leaving English strings where there's no translation available yet.
If we change something in the original text, the tool will update the table, removing the string that changed but keeping the numbering, adding the new string to the end:
1: Outerra Engine Alpha Tech Demo and Outerra Game
2:
3: Together with the demo we are launching a pre-alpha version of the first game that's running on the Outerra Engine.

Translators will then need to translate only the new appended strings. The tool that patches the files can be a part of outerra.exe and automatically patch the files at the beginning when it detects the files were changed.
