I was discussing inline XBRL with a client the other day when a thought occurred to me. GoFiler uses XDX to mark information in a document to convert it to inline XBRL at a later time, which is generally great, but it means if you have a line item on a table that doesn’t actually have a label (like a total line, for example), then GoFiler is just going to pick the standard label for that element. That’s not a bad thing, in and of itself, but if you want to customize the label, there needs to be some text on the line item for XDX to pick up. Adding hidden text to the document is a great way to add “hints” for XDX, without actually changing the look of the exported document.
