DotP2012: How to add new localization text?

I believe I have already seen this question in another topic, but it never got a clear answer. I'd like to know what I should do if I want to have the localization text for the names of the custom decks and for some new user queries (for example, "choose an untapped artifact you control" for Lodestone Myr activation) instead of the ugly [CAPITAL_TEXT_BETWEEN_PARENTHESES]. 
I looked at kev's mod and I saw that he achieved this goal by adding an XML Excel sheet called GLOSSARY.XML in the TEXT_PERMANENT directory. I did the same: made an XML Excel sheet and put it in the TEXT_PERMANENT directory of my custom DLC 1111, but nothing changed. Am I missing something? Do I have to mention this file elsewhere? I don't think the problem has to do with not having a custom campaign, since the default decks have the right names displayed also in the free duel mode.
