Various bitstream fields not marked in bold

[haasn]

The spec contains a number of fields with a field width (i.e. f(N)), but which are not marked as bold. These are, as follows:

• subsampling_x: f(1)
• subsampling_y: f(1)
• color_primaries: f(8)
• transfer_characteristics: f(8)
• matrix_coefficients: f(8)
• video_full_range_flag: f(1)
• point_y_scaling_bits_minus5: f(2)
• bits_per_ar_coeff_y_minus5 : f(2)
• bits_per_ar_coeff_cb_minus5: f(2)
• bits_per_ar_coeff_cr_minus5: f(2)

This is presumably an oversight in the spec, as the presence of a field width (and no other declaration) strongly suggests that they are intended as bitstream elements.
