The specs for the highly esoteric
Dynamic Delegation Discovery System (DDDS), RFCs 3401 to 3405 all
contain the following curious phrase:
The entire series of
documents is specified in "Dynamic Delegation Discovery System (DDDS)
Part One: The Comprehensive DDDS" (RFC 3401) . It is very
important to note that it is impossible to read and understand a
single document in that series without reading the related documents.
Since each document stating this is
itself a part of the series, recursion kicks in and it becomes
“impossible to read and understand” any of the RFCs.
This does not bode well for the rest of the standard.
