- identifier: A fan-made identifier in the [-_a-z0-9]* format. Not intended
for translation.
- latex: A formula in LaTeX syntax.
+
+A localizable text column is visible as two properties:
+The plural-name property (e.g. Pokemon.names) is a language-to-name dictionary:
+ bulbasaur.names['en'] == "Bulbasaur" and bulbasaur.names['de'] == "Bisasam".
+ You can use Pokemon.names['en'] to filter a query.
+The singular-name property returns the name in the default language, English.
+ For example bulbasaur.name == "Bulbasaur"
+ Setting pokedex.db.tables.default_lang changes the default language.
