One question: what does one do if one or more of the items listed above 
is missing  from the definition (e.g. an ISO or IEEE spec) of the metric 
we are referencing?  Leave the item(s) out?  Make it up ourselves (thus 
creating an "IETF" version of the metric by definition incompatible with 
the original)?
