I recently saw 'deprecate' used in an IANA Considerations and turned to "IANA Considerations" [RFC5226] to see how it was defined only to find no mention of it there. I am used to the term from SMI, as quoted below, but that seems not quite right, in that a deprecated IANA entry never disappears, as in http://www.iana.org/assignments/smi-numbers/smi-numbers.xhtml#smi-number s-5 Are there other, perhaps better definitions of the term 'deprecated' in use outside SMI (and yes, I know about praying nuns!)?
