Simon: this is exactly the kind of thing that people can use
architectural forms for.  The full version of AFs suffers from the
common SGML difficulty of trying to solve so many different problems
that the complexity of the solution becomes yet another problem;
however, a simplified profile, like the one I used for XAF (in
retrospect, I'd simplify that much further) would fit the bill nicely.

Basically, AFs let you declare that there exists a view of the
document (an "architecture") where elements and attributes might have
different names: you then declare what attribute(s) you will use to
represent the canonical names.  For example, using the simplified XAF
profile (and using pig-Portuguese, since I don't claim to speak or
understand the language),

  <?xml version="1.0"?>
  <?is10744:arch name="html"?>

  <texto html="html">
   <parte-dianteira html="front">
    <título html="title">Exemplo em Portugues</título>
   </parte-dianteira>
   <parte-principal html="body">
    <h1>Exemplo em Portugues</h1>
    <p>Este é um exemplo simples no português muito inábil.</p>
   </parte-principal>
  </texto>

The problem with using a schema is that you either kill light-weight
XML processing or force the translation to take place upstream, so the
client doesn't have the opportunity to take advantage of the
non-English material.  This example isn't all that complicated (though
the declaration syntax will have to change a bit) -- it might even be
fun to add namespaces to the mix.


All the best,


David
