+- markup: The format of a text column. Can be one of:

+  - markdown: Veekun's Markdown flavor (generally used in effect descriptions)
+  - gametext: Transcription of in-game text that strives to be both

+  - identifier: A fan-made identifier in the [-_a-z0-9]* format. Not intended

+  - latex: A formula in LaTeX syntax.
+- foreign: If set, the column contains foreign (non-English) text.
