Perhaps this should be called things that are wrong with this document, or things which should be improved. See the src/ROADMAP for notes on what is likely to be forthcoming in subsequent releases.
The internal document linking, while good, but could be better. Especially lame is the lack of an index. External links should be used more commonly where appropriate instead of sending users to the links page.
If you are looking for LARTC topics, you may find some LAR topics here, but you should try the LARTC page itself if you have questions that are more TC than LAR. Consult Appendix I, Links to other Resources for further references to available documentation.
