iSCSI: numeric-range format question (pedantic)

["Buck Landry" <blandry@crossroads.com>]

Is it draft 20's intent that any numeric-range may be represented by a single numerical-value, if that value is the only one acceptable?

I ask because:
-- the definition for numeric-range does not mention this (5.1)
-- OFMarkInt and IFMarkInt are defined as <numeric-range> for offers (A.3.2)
-- .. but the description for these keys says "In case it only wants a specific value, only a single value has to be specified".

There are three conclusions I might make:
a) When the draft says "only a single value has to be specified", it means only that (for instance) 4096~4096 might be specified.
b) x is valid shorthand for x~x, but only for OFMarkInt and IFMarkInt
c) x is valid shorthand for x~x, for any theoretical numeric-range

The safest choice is obviously c).  If the intent was actually a), would somebody please speak up.

Thanks, --buck
