An updated version of the document US GAAP Taxonomy - Tips, Tricks, and Traps is available.
Changes in the new version include building out the remaining networks (extended links) which were incomplete in the prior version, general proofreading edits.
If you had the draft of 2008-07-28, the first 34 pages really did not change much at all. The vast majority of the additions were after that point.
The authors of the document want to thank those who have provided comments and other feedback.
