Notes
-----
This allows to better appreciate only two 32b rows really form the Fraction part, leading to an overall type length of 128b instead of 160b as it could otherwise be misunderstood in the original figure.

---

The "+" vs "|" on the Fraction line would seem to improve consistency with packet layouts in other documents.
