[M4IF Technotes] question about the value of fixed_vop_time_increment

Hi,
We have a question regarding the number of bits for the representation of  VOP_time_increment_resolution
where its value is 1.
In the case of  vop_time_increment_resolution == 1  and fixed_vop_rate == 1 the sending of the bit for the fixed_vop_time_increment is redundant.
the only possible values of the vop_time_increment and fixed_vop_time_increment are in the range of [0,VOP_time_increment_resolution).In this case
the value is 0.
If we have the value of the VOP_time_increment_resolution == n , we need n-1 bits for the vop_time_increment representation.
In this special case the number of bits for the fixed_vop_time_increment is 0.
According the standard, what is the actual number of bits that need to specify the case of  VOP_time_increment_resolution=1 
	0 - since 0 is the minimum between [0 1) ?
or 
	1- since the value 0 is forbidden ?
Thanks in advance
 Leonid & Amit
