It is unclear to me what is the validation of binary datatypes, both from
the point of view of how it is currently
written in the spec, and from the point of view of how the WG intends
binary types to be validated. For
example, is a processor meant to throw an error when it encounters a
hex-encoded type whose value is
something like 2t ?
One argument against requiring such errors are that large binary objects,
such as those obtained from a
database, will be slow to process. The counter argument also seems valid,
i.e. that small binary objects
(e.g. 128 byte keys) should be checked, just like other datatypes.
Can someone say definitively what is intended by the spec?
