I don't think this is a good option... Things would get *really* ugly
when you insert a few hundred new elements :-)

And, as Frederick pointed out, it would only work with some collations

I mean that the directory structure always represents exactly what is in
the XML file -- nothing less and nothing more.

Static numbers would be additional information that is not in the XML
file, and gets lost when the translator exits. The same file gets
different representations, depending on what numbers were assigned in
the particular translator instance. Very undesirable.
