Granted, it is a small set of constraints, 9 in total, but it is a start. The interesting thing to me is that I could do this at all. The information on that rather large HTML page is extracted from SEC XBRL filings without even using an XBRL processor.
So, a beach head has been established. It seems to me that XBRL can in fact work to deliver on the promises made by its advocates (of which I am a member). I propose that these 5151 filings and the 9 constraints offer clues as to how to get the complete information set for all filers working like a Swiss watch.
