OK, my mistake.

Thank you.

I must admit that I haven't given much thought to enhancing the
vertical space. I tend to view levels and loggers as just
dimensions. Moreover, thought-experiments show that adding new
dimensions can be both economical and useful. The major problem is to
keep it simple enough to explain to a new log4j user.

I think Sun wasted much of its credibility by pushing not-so-standard
standards. People will eventually wake up to this fact.  Although you
probably did not make any new friends at Sun, your article will help
people come to that realization. Thanks for having had the courage to
write it.
