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.
