obviously 4096~4096 is also valid (but
redundant). Julo

Buck,

I coded it this way....

OFMarkInt=4096

If you don't fine the "~" delimiter then it is a single value.

I would interpret 4096~4096 as a range with only one acceptable value.

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
