Hi Eric,

Sorry I missed that.

I am not sure if the same protocol applies to IANA codepoints as RFCs, 
but if you were obsoleting an RFC it would need to be noted in the 
abstract and the introduction.

If you do a respin it might be better to note the deprecation near the 
text on obsolescence, since people tend to read the main text and not 
the IANA section. However at the end of the day it is up to the AD how 
they want to handle this.
