customize translations in l10n files

[Michael Wiedmann <mw@miwie.in-berlin.de>]

Is it possible to "customize" the translations of the l10n files for
individual documents?

E.g. how to override the translation of

<l:gentext key="Index" text="Stichwortverzeichnis"/>

in "de.xml" without changing this file.
