Welcome to 2010! I also want to state that I find the above text absolutely insulting to any programmer on this planet and even in galaxies far far away. > However, lower case is not acceptable for digit output. > Many early assemblers would not even accept lower case as valid input > digits except where the radix base exceeded 36 (thus exhausting all > upper case values).

There is nothing 'poor' about outputting lower case characters which are in the same optical spectrum as the numeric values of hex. I really do not support any such change and I sincerely hope that the RFC Editor removes this ad hominem attack to all programmers.
