Section 1.2 says:

           area A               area B              area C

It should say:

           area A               area B              area C
    <-------------------> <----------------> <------------------>

   Ingress-----A1----A2----AB1----B1----B2----BC1----C1----C2----Egress
   ^  \                / | \              / | \                /
   |   \              /  |  \            /  |  \              /
   |    A3----------A4--AB2--B3--------B4--BC2--C3----------C4
   |                     ^                  ^
   |                     |                  |
   |                     |                  |
   |                     |              ERO: (C3-strict, C4-strict,
   |                     |                    Egress-strict)
   |                     |              XRO: Not needed
   |                     |
   |               ERO: (B3-strict, B4-strict, BC2-strict, Egress-loose)
   |               XRO: (BC1, C1, C2)
   |
   ERO: (A3-strict, A4-strict, AB2-strict, Egress-loose)
   XRO: (AB1, B1, B2, BC1, C1, C2)


Notes:

The figure incorrectly shows the longest XRO to include the Egress as well.

The text in the RFC is correct - "....so the ERO and XRO signaled at Ingress could be (A3-strict, A4-strict, AB2-strict, Egress-loose) and (AB1, B1, B2, BC1, C1, C2), respectively. "

The editorial error exist in the figure.
