Is it possible to categorize modules and add interlanguage links to them, or is it just intended that be done with templates in the Template: namespace that use them?
EDIT: Tried adding them as normal. Showed up if you viewed the preview, but once published acted as non-code that crashed things to a halt. Tried putting them in --comments, but while they don't harm anything they don't function once published either.
EDIT AGAIN: I see on Wikipedia modules can have /doc pages to contain things like categorization, though I don't see anything on the module page that's an equivalent of {{Documentation}} to make it show up. I tried adding a /doc page to a Wikia module, but it just gets treated like another module.
