I agree and here are the two files I currently use (my parser succeeds
for all these tags). I suggest that they should be displayed in a
public place (is there a Web site for LTRU?) and added in a future
RFC.

Corrections and additions are of course very welcome, as well as test
reports from other implementations, so we can be sure we all use the
same language :-)
