I'm not covering setlocale in detail here, which is a basic i18n
prerequisite. In short, in main (), you need

 setlocale(LC_ALL, "" );

In the memory representation of the schema, which would be:

typedef struct {
...
   char *gettext_domain;
   char *gettext_directory;
} DConfSchema;

you should - upon parsing <gettext-domain/> and <gettext-directory/> set
the fields to its corresponding values. I'm not sure whether a DTD can
enforce to have a particular node ID only present once for a paticular
parent node - for these two tags this would be appropriate. After
parsing,

 bindtextdomain (schema->gettext_domain, schema->gettext_directory);
 bind_textdomain_codeset (schema->gettext_domain, "UTF-8");

would be called.

When parsing a DConf key,

typedef struct {
...
  char *description;
} DConfKey;

gets filled.

then, in the

const char *dconf_get_description (const char *key,
				   const char *locale);

getter you would then lookup the schema associated with key, and

 return dgettext (key->scheme->gettext_domain, key->description);

That's it :).
