Page 11: Section 2.5 Variable Precision Numbers
It seems possible that a variable-precision number could have
a size of 0 octets. Indeed, many of the examples given have
exactly that (e.g. the Validity-Choice field on pages 27--28 are
shown as 16-bits, which must be a size of 0). Yet the value
of such a quantity is undefined. Is it 0?
