While it seems it is quite normal to pepper all standard
documents/RFCs/JEPs with SHOULDs and SHOULD NOTs, I find it quite weird
that in practically none of the cases in which these words are used the
"full implications" are *explained*. Probably things would get too easy
then, with standards being fully comprehensible ;-).
