Remember:  This draft is only about text-processing.

No relevant computer can possibly have problems *parsing* a 64 bit
integer or 15 digit number.

They may not be able to deal with an object with that many bytes,
but the *semantics* of the numerical value parsed depends on the
header and limits and overflow handling should be defined in along
with the header.

Never attribute to malice what can adequately be explained by incompetence.
